drm/xe: forcewake debugfs open fails on xe_forcewake_get failure

A failure in xe_force_wake_get() no longer increments the domain's
refcount. Therefore, if xe_force_wake_get() fails during forcewake
debugfs open, return an error. This ensures there are no valid file
descriptors to close via forcewake debugfs, preventing refcount
mismanagement.

v3
- return xe_wakeref_t instead of int in xe_force_wake_get()

v5
- return unsigned int from xe_force_wake_get()

v6
- Use helper xe_force_wake_ref_has_domain()
to determine the status of the call.
