[Qemu-block] [PATCH v4 10/11] qemu-img: Set the ID of the block job in img_commit()

[Alberto Garcia]

img_commit() creates a block job without an ID. This is no longer
allowed now that we require it to be unique and well-formed. We were
solving this by having a fallback in block_job_create(), but now that
we extended the API of commit_active_start() we can finally set an
explicit ID and revert that change.
