Pull cred refcount updates from Christian Brauner:
 "For the v6.13 cycle we switched overlayfs to a variant of
  override_creds() that doesn't take an extra reference. To this end the
  {override,revert}_creds_light() helpers were introduced.

  This generalizes the idea behind {override,revert}_creds_light() to
  the {override,revert}_creds() helpers. Afterwards overriding and
  reverting credentials is reference count free unless the caller
  explicitly takes a reference.

  All callers have been appropriately ported"
