The device's hardward id was too short and because of that Windows didn't
load the driver if the device was hot-plugged in a different address.

balloon: bz#1167231: stop service on shutdown notification.

The balloon's service didn't take any action on SERVICE_CONTROL_SHUTDOWN
notification. This caused a BSOD when the verifier was used on the balloon
driver because the service didn't exit and kept an open file handle to
the driver.
