drm/xe/ct: serialise fast_lock during CT disable

The fast-path CT could be running as we enter a runtime-suspend or
potentially a GT reset, however here we only use the ct->fast_lock and
not the full ct->lock. Before disabling the CT, also serialise against
the fast_lock to ensure any in-progress work finishes before we start
nuking the CT related stuff. Once we disable ct->enabled and drop the
lock, any new work should fail gracefully, and anything that was in
progress should be finished.
