backend-drm: store udev_device in drm_kms_device

Browse source 
find_primary_gpu() and open_specific_drm_device() are currently
returning the udev_device while modifying the passed in drm_device. To
stop the modification, these functions should return drm_kms_device
directly, but the udev_device is also needed.
