Name nfs4_file-related helpers consistently. There are already nfs4_file_yada functions, so let's go with the same convention used by put_nfs4_file(): init_nfs4_file(). 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.
