modesetting: Consume all available udev events at once
We get multiple udev events for actions like docking a laptop into its
station or plugging a monitor to the station. By consuming as much
events as we can, we reduce the number of output re-evalutions.
I.e. having a Lenovo X250 in a ThinkPad Ultra Dock and plugging a
monitor to the station generates 5 udev events. Or having 2 monitors
attached to the station and docking the laptop generates 7 events.
It depends on the timing how many events can consumed at once.
