The function just needs to zero out metadata so that the blobstore is effectively destroyed. If the user wants to unmap the rest of the disk after the blobstore is destroyed, they are free to do so. On future initializations of blobstores the code will do the unmapping, so performance is not impacted. While here, implement the zeroing using the new write_zeroes functionality instead of allocating a buffer full of zeroes.
