qemu-img: do not zero-pad the compressed write buffer

bdrv_write_compressed() does not allow requests that span the end of the
device.  Therefore it is useless to zero-pad the last cluster and
thereby exceed the end of the device.

Let image formats handle zero-padding the final compressed cluster, if
necessary.
