[PATCH v3 04/23] drm/xe/hdcp: Update handling of xe_force_wake_get return

[Himal Prasad Ghimiray <himal.prasad.ghimiray@intel.com>]

With xe_force_wake_get() now returning the refcount-incremented
domain mask, the return value will be 0 for single domains (excluding
XE_FORCEWAKE_ALL) in the event of a failure. Modify the return
handling of xe_force_wake_get() accordingly and pass the return value as
input to xe_force_wake_put().

v3
- return xe_wakeref_t instead of int in xe_force_wake_get()
