Linux CM: Use kernel allocator directly

Browse Source 
In another few locations within the Linux portion of the cache
manager, directly use the kernel allocator. We can do so here
because we can guarantee that the amount of memory being allocated
is less than the page size, and there is a kfree() in all of the
exit paths, so we don't need the magic freeing behaviour, either.
