drm/xe/huc: Update handling of xe_force_wake_get return

xe_force_wake_get() now returns the reference count-incremented domain
mask. If it fails for individual domains, the return value will always
be 0. However, for XE_FORCEWAKE_ALL, it may return a non-zero value even
in the event of failure. Update the return handling of xe_force_wake_get()
to reflect this behavior, and ensure that the return value is passed as
input to xe_force_wake_put().

v3
- return xe_wakeref_t instead of int in xe_force_wake_get()

v5
- return unsigned int from xe_force_wake_get()

v7
- Fix commit message
