QtNetwork: disconnect other channels when network layer detected
With Happy Eyeballs we will connect one IPv4 and one IPv6 channel and
pick the network layer depending on which connects first. When the
first channel is connected we can close the other one.
Before this we let the other connection finish connecting and then
closed it. This will close the other one as soon as the first one
is connected.
