Revert "drm/xe/gt: Update handling of xe_force_wake_get return"

This reverts commit d42b44736ea29fa6d0c3cb9c75569314134b7732.

The reverted commit updated the handling of xe_force_wake_get to match
the new "return refcounted domain mask" semantics introduced in commit
a7ddcea1f5ac ("drm/xe: Error handling in xe_force_wake_get()"). However,
that API change only exists in 6.13 and later.

In 6.12 stable kernel, xe_force_wake_get still returns a status code.
The update incorrectly treats the return value as a mask, causing the
return value of 0 to be misinterpreted as an error. As a result, the
driver probe fails with -ETIMEDOUT in xe_pci_probe -> xe_device_probe
-> xe_gt_init_hwconfig -> xe_force_wake_get.
