History
Konstantin Belousov 603f963e56 The current default size of the nullfs hash table used to lookup the 
existing nullfs vnode by the lower vnode is only 16 slots.  Since the
default mode for the nullfs is to cache the vnodes, hash has extremely
huge chains.

Size the nullfs hashtbl based on the current value of
desiredvnodes. Use vfs_hash_index() to calculate the hash bucket for a
given vnode.
