Christian Brauner ba9ea771ec ovl: handle idmappings for layer lookup
Make the two places where lookup helpers can be called either on lower
or upper layers take the mount's idmapping into account. To this end we
pass down the mount in struct ovl_lookup_data. It can later also be used
to construct struct path for various other helpers. This is needed to
support idmapped base layers with overlay.
