drm/xe/tests/mocs: Update xe_force_wake_get() return handling
[ Upstream commit 6a966d677d06e96a81d430537abb5db65e2b4fda ]
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()
