disp: msm: sde: disable autorefresh on encoder disable

Browse Source 
Disable the autorefresh during encoder disable to avoid any
pending frame transfers while disabling. Additionally, handle
frame_done for new autorefresh frames to signal the fences and
proper accounting of pending_kickoff counter.
