drm/udl: Support DRM hot-unplugging

Browse source

Add drm_dev_enter() and drm_dev_exit() to the various modesetting
functions that interact with the device. After hot-unplugging the
device, these functions will return early. So far, the udl driver
relied on USB interfaces to handle unplugging of the device.
