[libvirt] [PATCH v3 1/4] qemu: block: propagate the delete flag to where it can actually be used

[Pavel Mores]

Propagate the delete flag from qemuDomainBlockCommit() (which was just
ignoring it until now) to qemuBlockJobDiskNewCommit() where it can be
stored in the qemuBlockJobCommitData structure which holds information
necessary to finish the job asynchronously.

In the actual qemuBlockJobDiskNewCommit() in this commit, we temporarily
pass a literal 'false' to preserve the current behaviour until the whole
implementation of the feature is in place.
