[PATCH v5 10/23] drm/xe/mocs: Update handling of xe_force_wake_get return

[Himal Prasad Ghimiray]

With xe_force_wake_get() now returning the refcount-incremented domain
mask, a return value of 0 indicates failure for single domains
(excluding XE_FORCEWAKE_ALL).

Modify the return handling of xe_force_wake_get() accordingly and pass
the return value to xe_force_wake_put().

v3
- return xe_wakeref_t instead of int in xe_force_wake_get()
- don't use xe_assert() to report HW errors (Michal)

v5
- return unsigned int from xe_force_wake_get()
- Remove redundant warn
