When the cache manager is shutting down, return an error to all
callback requests. Otherwise, it is possible for a callback to get
stuck waiting for a lock and when the lock clears to be left with
nothing but invalid memory addresses to crash on.
In the meantime, the file server is waiting for the response.

1. In multi-threaded applications deadlocking is always a problem.
Deadlock avoidance requires a strict adherence to a documented
hierarchy. The lock hierarchy for OAFW is described in a file
called locks.txt. There are two problems. First, some of the
locks are not included in locks.txt. Second, it is nearly
impossible given the depth of function calls for any programmer
to identify all of the locks that are held at any given time
a function is called. This patch implements a new locking order
verification mechanism. Each lock is assigned a lock level at
initialization. Each thread maintains a queue of held locks.
Each time a lock is acquired the queue is checked to ensure that
no locks with a higher level than the requested lock has already
been acquired. If a violation occurs, the service panics.
2. When the service panics ensure that a minidump will always be generated.
3. Remove unused lock cm_bufGetMutex.
4. The lock order verifier identified approximately a dozen
lock order violations that are corrected.
5. A race condition within the function path cm_GetSCache() ->
cm_GetNewSCache() -> cm_RecycleSCache() permitted a cm_scache_t
object to be issued simultaneously to two threads. This would
eventually result in a panic due to the resulting under count.
6. Fix interpretation of the empty string as the ioctl path to
mean the current directory. "fs lsm", "symlink list", etc.
now return a "not a ..." error instead of "does not exist".
7. Add SMB_STRF_SRCNULTERM flag to smb_ParseStringXXX functions
to indicate that the input string is a nul terminated string.
Assign it when input strings are nul terminated.
8. The CIFS protocol specification for handling NT_TRANSACT_CREATE
does not match the observed behavior. The 'nameLength' is specified
in bytes not in characters. Fix the implementation to match.
9. The cm_HaveAccessRights() attempt at deadlock avoidance by calling
lock_TryRead() on the parent directory cm_scache_t rw-lock does not
avoid the deadlock. Avoid the deadlock by enforcing the lock order
of lowest vnode first. Then remove the infinite loop avoidance in
cm_SyncOp() that was returning an unwarranted access denied error.

Prevent rxi_MorePacketsNoLock() from dereferencing a NULL pointer if
the requested allocation size cannot be satsified. In that case back
off the number of packets until osi_Alloc() succeeds or panic if no
packets can be allocated at all.
In AllocPacketBufs() do not transfer more than rx_TSFPQGlobSize packets.
Modify RX_TS_FPQ_GTOL2() macro to protect against transfering more packets
that are actually free.
Modify RX_TS_FPQ_COMPUTE_LIMITS() to enforce a rx_TSFPQGlobSize maximum
value of 64 packets to prevent ever increasing allocation sizes within
AllocPacketBufs()
