drm/msm/sde: remove thread flush request for same thread



Input event work is scheduled on crtc_commit thread and
encoder disable API tries to flush the input work. This
can cause deadlock to crtc_commit thread because it may
wait for pending job on its own thread. Fix this deadlock
by removing the flush_kthread API call.
