vhost: fix IOTLB mempool single-consumer flag

Control thread (which handles iotlb msg) and forwarding thread
both use iotlb to translate address. The former may modify the
same entry of mempool and may cause a loop in iotlb_pending_entries
list.

Bugzilla ID: 523
Fixes: d012d1f293f4 ("vhost: add IOTLB helper functions")
