drm/bridge: anx7625: Zero error variable when panel bridge not present
While parsing the DT, the anx7625 driver checks for the presence of a
panel bridge on endpoint 1. If it is missing, pdata->panel_bridge stores
the error pointer and the function returns successfully without first
cleaning that variable. This is an issue since other functions later
check for the presence of a panel bridge by testing the trueness of that
variable.
In order to ensure proper behavior, zero out pdata->panel_bridge before
returning when no panel bridge is found.
