The device reset may fail in virtio-vdpa case now, so add checks to
its return value and fail the register_virtio_device().

So the reset() would be called by the driver during remove as well, or
is it sufficient to deal only with the reset during probe?

Actually there is no way to handle failure during removal. And it
should be safe with the protection of software IOTLB even if the
reset() fails.

If this is true, does it mean we don't even need to care about reset 
failure?

Thanks
