vhost I/O only need to be split on 2MB boundaries if there is a break in the VM's memtable at that 2MB boundary. This should drastically reduce (if not eliminate) the intermittent test pool failures seen recently. virtio limits number of segments to 128, but this 2MB splitting could introduce additional segment breaks which we do not allocate IOVs for. In almost all cases, there are no memtable breaks except at low 2MB, so most of the extra segment breaks we are adding are unnecessary.
