When ports are defined in the tcpc main node, fwnode_usb_role_switch_get returns an error, meaning usb_role_switch_get (which would succeed) never gets a chance to run as port->role_sw isn't NULL, causing a regression on devices where this is the case.

Fix this by turning the NULL check into IS_ERR_OR_NULL, so usb_role_switch_get can actually run and the device get properly probed.
