Anatol Belski 8acefad893 block: qcow: Test freed clusters stay on the free list
After churning a single L2 region with an fsync per write, scan the file
for refcount==0 clusters and assert every one is on the runtime free
list. The reuse bug left relocated refcount block clusters free on disk
but off the list, so this fails without the fix, reporting the exact
count of stranded clusters.
