[libvirt] [PATCH RFC 20/51] qemu: blockjob: Add reference to disk into struct qemuBlockJobData

[Peter Krempa]

Block jobs can also happen on objects which are not a disk at a given
point (e.g. the frontend was not hotplugged yet) and thus will be
eventually kept separately. Add a reference back to the disk for
blockjobs which do correspond to a disk.
