drm/xe: Do clean shutdown also when using flr

Currently Xe driver is triggering flr without any clean-up on
shutdown. This is causing random warnings from pending related works as the
underlying hardware is reset in the middle of their execution.

Fix this by performing clean shutdown also when using flr.
