qcow2: Assert that cluster operations are aligned
We already audited (in commit 0c1bd469) that qcow2_discard_clusters()
is only passed cluster-aligned start values; but we can further
tighten the assertion that the only unaligned end value is at EOF.
Recent commits have taken advantage of an unaligned tail cluster,
for both discard and write zeroes.
