compositor-drm: Don't do a mode set on drm_output_switch_mode()

At this point, we reallocated the gbm surface, but we don't have an
fb with the right size to use. If we're going to a larger mode, the fb
would be too small and the mode set would fail. Besides, the repaint
logic will already do a mode set if necessary, so rely on that instead.
