Amir Goldstein 1248ea4b91 ovl: pass layer mnt to ovl_open_realfile()
Ensure that ovl_open_realfile() takes the mount's idmapping into
account. We add a new helper ovl_path_realdata() that can be used to
easily retrieve the relevant path which we can pass down. This is needed
to support idmapped base layers with overlay.
