......................................................................
iservice: use saved iface index to restore metric
When adding block rules, the interface metric of the VPN adapter is
temporarily modified so that an old version of Windows 10 would pick
it up first when looking up stuff via DNS. These metrics are reverted to
the old value when the block is removed.
When reverting them, instead of using the stored interface index where
the original values were read from, we were using the interface index
passed to the service with the wfp block message. That index could
theoretically be different from the one stored, which would result in
the metric being set to the wrong interface.
