The bdev_lvol_grow_lvstore will grow the lvstore size if the undering bdev size is increased. It invokes spdk_bs_grow internally. The spdk_bs_grow will extend the used_clusters bitmap. If there is no enough space resereved for the used_clusters bitmap, the api will fail. The reserved space was calculated according to the num_md_pages at blobstore creating time.
