adb: improve race between device_connected and device_disconnected.

If a device is unplugged while it's being processed, we can be inside
register_usb_transport still when we call unregister_usb_transport,
leading to bad things happening. Move the call of
register_usb_transport into the scope guarded by usb_handles_mutex.
