Migrate in-tree consumers of BNetworkDevice::GetNextNetwork to GetNetworks.

GetNextNetwork is very inefficient as it fetches all networks but only
returns one of them. GetNetworks was introduced to compensate for that,
but only the most regular consumers were initially migrated. Now,
the remaining consumers of the old API are converted to the new one.
