mds: don't rdlock_try authlock for path_traverse permission check

We don't actually check anything anyway, just ping the lock.

If the client is trusted with AUTH_EXCL, this is pointless anyway.
It is only really useful with untrusted (e.g., fuse) clients, but
they'll need some sort of special support for that later.
