[PATCH v2 0/2] MR1985: Fix regression in Iphlpapi where the Ipv4Enabled and Ipv6Enabled flags are not set.

[Santino Mazza (＠tati1454)]

This regression occurred in the commit 091c92521ee22558bbc2adcdd8b18b213d818180 (`iphlpapi: Implement GetAdaptersAddresses() on top of nsi.`) This affects some dotnet core applications which make use of NetworkInterface.Supports which returns false when an interface supports IPv4 or IPv6.

Could these test be moved to the `while (ua)` loop of `test_GetAdaptersAddresses()` since we're testing `GetAdaptersAddresses()` not `GetUnicastIpAddressEntry()`?
