[usb] Use port->disconnected to check for disconnected devices
The usb_message() and usb_stream() functions currently check for
port->speed==USB_SPEED_NONE to determine whether or not a device has
been unplugged. This test will give a false negative result if a new
device has been plugged in before the hotplug mechanism has finished
handling the removal of the old device.
Fix by checking instead the port->disconnected flag, which is now
cleared only after completing the removal of the old device.
