The function vmbus_exists() was introduced recently to deal with cases where the vmbus driver failed to initialize and yet other Hyper-V drivers attempted to register with the vmbus bus driver. This patch introduced a bug where vmbus_driver_unregister() would fail to unregister the driver. This patch fixes the problem.
