drm/amdkfd: fix restore worker race condition In free memory of gpu path, remove bo from validate_list to make sure restore worker don't access the BO any more, then unregister bo MMU interval notifier. Otherwise, the restore worker will crash in the middle of validating BO user pages if MMU interval notifer is gone.
