[PATCH v7 12/26] drm/xe/tests/mocs: Update xe_force_wake_get() return handling

With xe_force_wake_get() now returning the refcount-incremented domain
mask, a return value of 0 indicates failure for single domains.
Change assert condition to incorporate this change in return and
pass the return value to xe_force_wake_put()

v3
- return xe_wakeref_t instead of int in xe_force_wake_get()

v5
- return unsigned int for xe_force_wake_get()
