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.
