msm: mdss: Fix the issue of recovery from DCM state

Browse source 
In the QDCM tool, toggling from DCM state to DTM state fails
because system unblank doesn't happen successfully. The root
cause of the issue is at the DCM_BLANK, the overlay_off is called
before setting the panel_power_state to OFF, due to which
overlay_off doesn't suspend properly. Therefore, rearrange the
order to fix the problem.
