[PATCH] Race against parent deletion in key_user_lookup()

I looked at some of the oops reports against keyrings, I think the problem
is that the search isn't restarted after dropping the key_user_lock, *p
will still be NULL when we get back to try_again and look through the tree.

It looks like the intention was that the search start over from scratch.
