ControlDevice: Fix removal of redirection on hub unplug

On unplug of USB hub that contains a redirected device, removal of redirection is started when redirected device PDO is still present in UsbDk device lists. In this case UsbDk will try to send reset IOCTL to this device and system will return STATUS_NO_SUCH_DEVICE error code. This commit changes behavior of redirection removal logic in a way that it will not interrupt removal process when such an error is returned by reset.
