Jason Wang f83c85ee73 vhost: allow batching hint without size 
commit 95932ab2ea upstream.

Commit e2ae38cf3d ("vhost: fix hung thread due to erroneous iotlb
entries") tries to reject the IOTLB message whose size is zero. But
the size is not necessarily meaningful, one example is the batching
hint, so the commit breaks that.

Fixing this be reject zero size message only if the message is used to
update/invalidate the IOTLB.

Fixes: e2ae38cf3d ("vhost: fix hung thread due to erroneous iotlb entries")
