The debugfs api for mst control is a multi stage process where the connector id is selected using the mst_con_id node, which is then used on other commands such as edid_modes_mst for mode switch. During mode switch control, the mode is set using the current id for a display and then the switch is initiated through an unplug and replug. But on an unplug the connector is destroyed and a new id is assinged for that display on the subsequent plug. This change detects this scenario and updates the cached connector id with the id from the newly created connector.
