[hyperv] Ignore unsolicited VMBus messages

In some high-end Azure instances (e.g. NC6) we may receive an
unsolicited VMBUS_OFFER_CHANNEL message for a PCIe pass-through device
some time after completing the bus enumeration.  This currently causes
apparently random failures due to unexpected VMBus message types.

Fix by ignoring any unsolicited VMBus messages.
