Ignore HID connection states from unselected transports

When HID transports are switched, it is possible the newly selected transport connects before the previous transport disconnects. As a result the wrong HID connection state may be broadcasted to apps.
This fix now moves the previous transport to the DISCONNECTED  state immediately and ignores further state transitions from the native HID for the same transport.
