usb: gadget: f_serial: Ensure gserial disconnected during unbind
Some UDCs may return an error during pullup disable as part of the
unbind path for a USB configuration. This will lead to a scenario
where the disable() callback is skipped, whereas the unbind() still
occurs. If this happens, the u_serial driver will continue to fail
subsequent binds, due to an already existing entry in the ports array.
Ensure that gserial_disconnect() is called during the f_serial unbind,
so the ports entry is properly cleared.
