Attempting to enqueue a CLEANUP message while the GuC is stopped
(during a device reset or suspend) triggers a missing outer runtime
PM protection warning in xe_pm_runtime_get_noresume().

Since the GuC cannot service Command Transport (CT) requests while
stopped, skip the message and route directly to local teardown.

Fixes: d930c19fdff3 ("drm/xe: Build PM into GuC CT layer")
