Fix a witness warning when expanding a hash table.  We were allocating the new
hash while holding the lock on a zone.  Fix this by doing the allocation
seperately from the actual hash expansion.

The lock is dropped before the allocation and reacquired before the expansion.
The expansion code checks to see if we lost the race and frees the new hash
if we do.  We really never will lose this race because the hash expansion is
single threaded via the timeout mechanism.
