drm/msm/sde: fix unwanted panic in case of ESD failure

Currently in driver if ESD thread has detected panel failure,
then from commit thread the panel status check API returns early.
This unnecessarily causes panic, if ping pong transfer timeout has
happened because of panel failure. Fix this by adding check
for any pending ESD recovery sequence in panel status check API.
