Christian Brauner e5b310b512 fs: add two trivial lookup helpers ...

commit 00675017e0aeba5305665c52ded4ddce6a4c0231 upstream.

Similar to the addition of lookup_one() add a version of
lookup_one_unlocked() and lookup_one_positive_unlocked() that take
idmapped mounts into account. This is required to port overlay to
support idmapped base layers.
