[libvirt] [PATCH RFC 02/51] qemu: blockjob: Emit VIR_DOMAIN_EVENT_ID_BLOCK_JOB only for local disks

[Peter Krempa]

The event reports the disk path to identify the disk which makes sense
only for local disks. Additionally network backed disks like NBD don't
need to have a path so the callback would return NULL.

Report VIR_DOMAIN_EVENT_ID_BLOCK_JOB only for non-empty local disks.
