Fix handling usb notification after pr_swap complete

After the device (USB host) finished the pr_swap and the power
role is changed from Source to Sink, the notification should be
updated with different messages. However, the notification may be
ignored since the charger type is not USB. Users may get
confused when the notification is gone.

If the peripheral device is still connected, UsbDeviceManager
should push new notification.
