[PATCH] knfsd: change nlm_file to use a hlist

Browse Source 
This changes struct nlm_file and the nlm_files hash table to use a hlist
instead of the home-grown lists.

This allows us to remove f_hash which was only used to find the right hash
chain to delete an entry from.

It also increases the size of the nlm_files hash table from 32 to 128.
