NFSD: Add a nfsd4_file_hash_remove() helper

Browse source

Refactor to relocate hash deletion operation to a helper function
that is close to most other nfs4_file data structure operations.

The "noinline" annotation will become useful in a moment when the
hlist_del_rcu() is replaced with a more complex rhash remove
operation. It also guarantees that hash remove operations can be
traced with "-p function -l remove_nfs4_file_locked".

This also simplifies the organization of forward declarations: the
to-be-added rhashtable and its param structure will be defined
/after/ put_nfs4_file().
