Vinicius Costa Gomes c5b28fc161 ovl: Optimize override/revert creds 
Use override_creds_light() in ovl_override_creds() and
revert_creds_light() in ovl_revert_creds().

The _light() functions do not change the 'usage' of the credentials in
question, as they refer to the credentials associated with the
mounter, which have a longer lifetime.

In ovl_setup_cred_for_create(), do not need to modify the mounter
credentials (returned by override_creds_light()) 'usage' counter.
Add a warning to verify that we are indeed working with the mounter
credentials (stored in the superblock). Failure in this assumption
means that creds may leak.
