[libvirt] [PATCH 4/4] qemu: Use data in qemuBlockJobDataPtr instead of re-generating job name

[Peter Krempa]

qemuDomainBlockPivot and qemuDomainBlockJobAbort need the job name for
cancelling or pivoting but were generating it locally instead of
accessing the existing copy in the job data structure.
