This reverts commit deb05f8431f31e08fd6ab99a56069fc98014dbec.

The helper function introduced in the reverted commit is for handling
the "refcounted domain mask" introduced in commit a7ddcea1f5ac
("drm/xe: Error handling in xe_force_wake_get()"). Since that API change
only exists in 6.13 and later, this helper is unnecessary in 6.12 stable
kernel.
