kernel/user.c: clean up some leftover code
The out_unlock label is misleading; no unlocking happens after it, so
just return NULL directly.
Also, nothing between the kmem_cache_zalloc() that creates new and the
two key_put() can initialize new->uid_keyring or new->session_keyring,
so those calls are no-ops.
