Patch adbd for handling usb disconnection

[lucarin91]

The adbd seems unable to handle USB client disconnection, without rebooting.

To reproduce the issue do the following:

adb shell
adb kill-server
adb shell

After that, it is not possible to connect again till the board or service is restarted.

It seems that the adbd service return the following error, and doesn't accept a new USB connection.
