History
Derrick Brashear 12fa5b859b xvcb lock order violation 
afs_FlushVCBs(1) = xvcb, xserver (in that order)

afs_GetServer = xserver, xsrvAddr, (call afs_RemoveSrvAddr which calls
afs_FlushServer, which gets xvcb)

"nope". do a little dance to get xvcb, searching for a struct server to reuse
again if we had to block.

if you're curious:
Lock afs_xserver status: (reader_waitingwriter_waiting, write_locked(pid:1589 at:36), 3 waiters)
Lock afs_xvcb status: (none_waiting, write_locked(pid:0 at:273))
Lock afs_xsrvAddr status: (none_waiting, write_locked(pid:1589 at:116))
