    drm/xe: Use atomic instead of mutex for xe_device_mem_access_ongoing
    
    xe_guc_ct_fast_path() is called from an irq context, and cannot lock
    the mutex used by xe_device_mem_access_ongoing().
    
    Fortunately it is easy to fix, and the atomic guarantees are good enough
    to ensure xe->mem_access.hold_rpm is set before last ref is dropped.
    
    As far as I can tell, the runtime ref in device access should be
    killable, but don't dare to do it yet.
