disp: msm: reset connector panel_dead during dsi bridge post disable

This change resets panel_dead property at the end of dsi bridge post disable.
Currently as part of the ESD recvoery sequence, dsi_bridge_enable resets this
property, but WD vsync source is selected before this point based on the older
panel_dead status. With this change, panel_dead will be in a proper state and
the correct vsync source will be selected during recovery.
