board list command fails if there's no active network connection #1612
Description
Bug Report
Current behavior
$ arduino-cli board list
Error detecting boards: Error getting board list: [listing ports from discovery builtin:mdns-discovery: command failed: mdns lookup error: failed to bind to any unicast udp port]
board list commands returns an error when called with no active network connection, this happens because the mdns-discovery process searches for boards in the currently active local network.
Expected behavior
board list error doesn't return errors if mdns-discovery can't find an active network connection.
