From: Michel Dänzer <michel.daen...@amd.com>
If disabling a CRTC had to be deferred due to a pending flip in
drmmode_crtc_dpms, there may no longer be any outputs associated with
the CRTC when we get here. So we have to check for !crtc->enabled and
call drmmode_crtc_dpms in that case as well.
Fixes: 9090309e057d ("Wait for pending flips to complete before turning
off an output or CRTC")
