drm/msm/sde: Restarting ESD status check after Doze mode 



In the current implementation when display enters Doze mode
ESD status check thread is disabled. When it exits from the
Doze mode an unblank call is made to enable ESD status check
but it is not getting enabled so this change fixes the issue.
