[PATCH xf86-video-ati 2/2] Move DPMS check from radeon_scanout_do_update to radeon_scanout_flip

[michel@xxxxxxxxxxx (Michel Dänzer)]

From: Michel Dänzer <michel.daenzer@xxxxxxx>

When radeon_scanout_do_update is called from
drmmode_crtc_scanout_update, drmmode_crtc->pending_dpms_mode may still
be != DPMSModeOn, e.g. during server startup.

Fixes intermittently showing garbage with TearFree enabled.
