This becomes especially useful when accidentally
trying to use vhost-blk socket as a vhost-scsi one.
There's no SCSI/Block identification within the protocol,
so blk messages can be interpreted as scsi ones.
This usually results in a bdev being created with
bs==0 && blocksize==0 and leads to a crash.
Nevertheless, this extra check should be here to protect
against malicious/incomplete vhost-scsi targets crashing
entire initiator apps.

This is the first step toward fixing the behavior of the lvol bdev
module so that it handles spdk_bdev_unregister() correctly.
Currently, when an lvol bdev is unregistered, this causes the associated
lvol to be deleted; this isn't the desired behavior, since
spdk_bdev_unregister() is just meant to drop the currently-exposed bdev,
as in a hot-unplug event, not destroy the backing storage.
The current implementation of the new destroy_lvol_bdev method still
calls into the exsting (broken) spdk_bdev_unregister() path, but this at
least lets us fix the existing delete_bdev RPC callers that really
intended to destroy the lvol.
The next step is to make vbdev_lvol_destroy() call spdk_lvol_destroy()
instead of unregistering the bdev, which will require cleanup in the
generic lvol layer to remove the close_only flag.
