[PATCH xf86-video-ati 06/21] Update RandR CRTC state if set_mode_major fails in set_desired_modes

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

Without this, RandR would report the CRTC and its outputs as enabled,
even though they were actually off due to the failure.

(Cherry picked from amdgpu commit 4dcda0b48d62944c841cd9540f4ad4c7ac8dee47)
