ovl: add override_creds cleanup guard extension for overlayfs

Browse source

Overlayfs plucks the relevant creds from the superblock. Extend the
override_creds cleanup class I added to override_creds_ovl which uses
the ovl_override_creds() function as initialization helper. Add
with_ovl_creds() based on this new class.
