[Intel-gfx] [PATCH] lib: Reset 'position_changed' after a drmModeSetCrtc()

[Damien Lespiau]

So the next commit won't trigger a drmModeSetCrtc() if the primary plane
doesn't have any update needing it.

This shouldn't be a problem at the moment as we don't allow the primary
plane to be of a different size than the CRTC viewport, but it will most
likely change in the future and we don't want to have that bug there.
