description:
When unloading the nfsserver module, call nfs_fini() so that the nfsrvdescpl
pool gets destroyed. Otherwise we are left with a stray pool that points to
unmapped memory behind (and bad things happen). Typically you get seemingly
random page faults (without printing uvm_fault) that happen in various pool
operations. Most frequent one is the pool_drain() from the page daemon.
