drm_queue_handler just puts the event on the signalled list; without
calling drm_queue_handle_deferred, actual processing of the event may be
delayed indefinitely, e.g. until another event arrives from the kernel.
This could result in DRI2 clients hanging during DPMS off.
Fixes: ba83a866af "Add radeon_drm_handle_event wrapper for
drmHandleEvent"
