wlr_output_damage: Don't schedule a new frame if damage region does not intersect with output

Browse source 
This fixed adaptive sync issues with wlr_scene. Scenes don't check
if the damage region intersects with an output when calling
wlr_output_damage_add.

This is especially important for multi output.
