Anatol Belski 2ea2209920 block: qcow: Test reopen finds no stranded clusters
After churning a single L2 region with an fsync per write, close and
reopen the image. parse_qcow rebuilds the free list from the on disk
refcounts, so a reopen that recovers many clusters means the runtime
allocator stranded them. Without the fix the reopen recovered every
relocated cluster. Now it finds none.
