With the current code such requests are allowed and we hit an
assertion:
$ qemu-img create -f qcow2 img.qcow2 1M

Subject: [PATCH v2] qcow2: Check request size in
qcow2_co_pwritev_compressed_part()
When issuing a compressed write request the number of bytes must be a
multiple of the cluster size or reach the end of the last cluster.
With the current code such requests are allowed and we hit an
assertion:
$ qemu-img create -f qcow2 img.qcow2 1M
$ qemu-io -c 'write -c 0 32k' img.qcow2
