Re: [libvirt] [PATCH] qemu_migration: Avoid writing to freed memory

When a domain is killed on the source host while it is being migrated
and libvirtd is waiting for the migration to finish (waiting for the
domain condition in qemuMigrationSrcWaitForCompletion), the run-time
state including priv->job.current may already be freed once
virDomainObjWait returns with -1. Thus the priv->job.current pointer
cached in jobInfo is no longer valid and setting jobInfo->status may
crash the daemon.
