drm/udl: drop drm_driver.release hook
There's only two functions called from that: drm_kms_helper_poll_fini() and udl_free_urb_list(). Both of these are also called from the ubs_driver->disconnect hook, so entirely pointless to do the same again in the ->release hook. Furthermore by the time we clean up the drm_driver we really shouldn't be touching hardware anymore, so stopping the poll worker and freeing the urb allocations in ->disconnect is the right thing to do. Now disconnect still cleans things up before unregistering the driver, but that's a different issue. v2: Use _fini, not _disable in unplug, motivated by discussions with Thomas. _disable/_enable are for suspend/resume.
