Yu Li e98ea329bf block: qcow: read from the backing file if present on read miss ...

Reads to qcow files with backing files will fall through to the backing
file if there is no allocated cluster. As of this change, a write will
still trash the cluster and hide any data already present.

This commit is based on crosvm implementation:
