vmbus: Print a warning when enabled without the recommended set of features
Some Windows versions crash at boot or fail to enable the VMBus device if they don't see the expected set of Hyper-V features (enlightenments). Since this provides poor user experience let's warn user if the VMBus device is enabled without the recommended set of Hyper-V features. The recommended set is the minimum set of Hyper-V features required to make the VMBus device work properly in Windows Server versions 2016, 2019 and 2022.
