msm: mdss: Prevent race condition between dsi off and bta status check
fb_event_callback() is what is responsible for cancelling the
delayed_work when it gets the FB_BLANK_POWERDOWN event. However,
this event occurs after the panel & DSI have been turned off. So
if the check_status function was being called right when the panel
is being turned off, we have a race conditon. Hence check
shutdown flag to avoid bta status check when dsi is being turned off.
