[IMP] hw_driver: inform the odoo instance of connected and disconnected devices

Before this commit, we only sent the list of connected devices to
the odoo instance (thanks to `self.send_alldevices`) when a device
is newly connected. Now, we also send this list when a device is
disconnected. We also try to call this method once if multiple devices
are connected/disconnected during an iteration.
