drm/radeon/cik: properly set sdma ring status on disable
commit 7b1bbe883b3ed962ca2be4daf321f318f5091340 upstream. When we disable the rings, set the status properly. If not other code pathes may try and use the rings which are not functional at this point. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Jiri Slaby <jslaby@suse.cz>
