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.
