disp: msm: sde: set watchdog TE when panel fails ESD check

Browse Source 
In the event of panel dead scenario, it is possible to receive a
mode set call before the panel has recovered. When this happens,
display should select watchdog TE as the vsync source.

Similarly when detecting a write pointer timeout, if the panel is
dead then watchdog TE should be or has already been configured and
display should not make a change to this vsync selection.
