Patch

Far Cry 5 fails to connect to online mode due to the missing part of
initialization which is done from NotifyUnicastIpAddressChange() callback. The
callback is supposed to be called right away if InitialNotification flag is
set.

The attached patch fixes the issue.

Far Cry 5 online mode also requires BCryptSecretAgreement(ECDH) and
BCryptDeriveKey(KDF_HASH, SHA1 hash) implementation, which is Bug #47699.
