nfsd_client_rmdir() open-codes a subset of simple_recursive_removal().
Conversion to calling simple_recursive_removal() allows to clean things
up quite a bit.
While we are at it, nfsdfs_create_files() doesn't need to mess with "pick
the reference to struct nfsdfs_client from the already created parent" -
the caller already knows it (that's where the parent got it from,
after all), so we might as well just pass it as an explicit argument.
So __get_nfsdfs_client() is only needed in get_nfsdfs_client() and
can be folded in there.
Incidentally, the locking in get_nfsdfs_client() is too heavy - we don't
need ->i_rwsem for that, ->i_lock serves just fine.
