drm/xe/xe_reg_sr: Update handling of xe_force_wake_get return

Browse source

With xe_force_wake_get() now returning the refcount-incremented
domain mask, a non-zero return value in the case of XE_FORCEWAKE_ALL does
not necessarily indicate success. Use xe_force_wake_ref_has_domain()
to determine the status of the call.

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()
- xe_force_wake_put() error doesn't need to be checked. It internally
WARNS on domain ack failure.

v5
- return unsigned int from xe_force_wake_get()

v6
- use helper xe_force_wake_ref_has_domain()
