drm/udl: Unregister device before cleaning up on disconnect
Disconnecting a DisplayLink device results in the following kernel
error messages
[ 93.041748] [drm:udl_urb_completion [udl]] *ERROR* udl_urb_completion - nonzero write bulk status received: -115
[ 93.055299] [drm:udl_submit_urb [udl]] *ERROR* usb_submit_urb error fffffffe

coming from KMS poll helpers. Shutting down poll helpers runs them
one final time when the USB device is already gone.
Run drm_dev_unplug() first in udl's USB disconnect handler. Udl's
polling code already handles disconnects gracefully if the device has
been marked as unplugged.
