Set drmmode_crtc->scanout_id = 0 when TearFree is disabled
When disabling TearFree, drmmode_crtc->scanout_id could remain as 1,
but drmmode_set_mode_major would destroy drmmode_crtc->scanout[1], so
scanout_do_update() would keep bailing, and the scanout buffer would
stop being updated.
Fixes freeze after disabling TearFree on a CRTC with active RandR
rotation or other transform.
