Yu Li 5ffc6d6107 block: qcow: initialize qcow clusters off the backing file when present ...

This preserves any data that the backing file had on a cluster when
doing a write to a subset of that cluster. These writes cause a
performance penalty on creating new clusters if a backing file is
present.

This commit is based on crosvm implementation:
