This helps prepare using the bdev test tools (bdevio and bdevperf) with a virtio/vhost-scsi initiator. For virtio initiators running in the host OS, SPDK must open file descriptors for every hugepage to pass to the vhost target. vhost typically limits the number of memory regions to 8 - meaning 2MB hugepages generally will not work, but even for 1GB hugepages we need to limit it so that we do not default to trying to use all of the hugepages.
