Stefan Hajnoczi f4d38bef7c qcow2: allow sub-cluster compressed write to last cluster
Compression in qcow2 requires image length to be a multiple of the
cluster size.  Lift this requirement by zero-padding the final cluster
when necessary.  The virtual disk size is still not cluster-aligned, so
the guest cannot access the zero sectors.
