[PATCH 4/4] drm/qxl: add drm_driver.release callback.

[Gerd Hoffmann]

Move final cleanups to qxl_drm_release() callback.
Add drm_atomic_helper_shutdown() call to qxl_pci_remove().

Reorder calls in qxl_device_fini().  Cleaning up gem & ttm
might trigger qxl commands, so we should do that before
releaseing command rings.
