[PATCH v2 1/2] drm/xe: Ensure caller uses sole domain for xe_force_wake_assert_held

[Himal Prasad Ghimiray]

xe_force_wake_assert_held() is designed to confirm a particular
forcewake domain's wakefulness; it doesn't verify the wakefulness of
multiple domains. Make sure the caller doesn't input multiple
domains(XE_FORCEWAKE_ALL) as a parameter.

v2
- use domain != XE_FORCEWAKE_ALL (Michal)
