NFSD: Clean up nfsd4_init_file()

Name this function more consistently. I'm going to use nfsd4_file_
and nfsd4_file_hash_ for these helpers.

Change the @fh parameter to be const pointer for better type safety.

Finally, move the hash insertion operation to the caller. This is
typical for most other "init_object" type helpers, and it is where
most of the other nfs4_file hash table operations are located.
