Commit 605e806166847872bb91831b397d58f95027975a broke the mkfs.btrfs -r option, because it calls make_btrfs without ever setting dev_block_count, in the -r case, so we tell it to make a filesystem of size 0. Then we wander into ENOSPC land and segfault. As a quick one-line-fix, just set the dev_block_count to the size of the destination image file.
