drm/udl: delete dead code

Browse Source 
The "unode" pointer cannot be NULL here and checking for it causes
Smatch warnings:

   drivers/gpu/drm/udl/udl_main.c:259 udl_get_urb_locked()
   warn: can 'unode' even be NULL?

Fortunately, it's just harmless dead code which can be removed.  It's
left over from commit c5c354a3a472 ("drm/udl: Fix inconsistent urbs.count
value during udl_free_urb_list()").
