Reuse network configurations set on device if possible

Don't allow reconfiguring the network on the device without a reset in
between. It wouldn't lead to a working configuration, since the host has
already gotten an IP from the existing configuration at this point.

But if the already configured network happens to be free, use it. This
allows devices to work keeping the same address even if host qdb is
restarted.

This doesn't guard against the possibility that the existing
configuration conflicts with a network already in place. But telling
apart that situation would be too difficult: How to tell whether the
network is the device or something else? In that case the user just
has to replug the device. Then it will pick an unused subnet.
