From: "Dr. David Alan Gilbert" <dgilb...@redhat.com> In e91d895 I added the new pause-before-switchover mechanism to allow migration completion to be delayed; this changes the last state prior to completion to MIGRATE_STATUS_DEVICE rather than MIGRATE_STATUS_ACTIVE.
Fix the failure path in migration_completion to recover the block devices if it fails in MIGRATE_STATUS_DEVICE, not just the MIGRATE_STATUS_ACTIVE that it previously had. This corresponds to rh bz: https://bugzilla.redhat.com/show_bug.cgi?id=1538494 whose symptom is an occasional source crash on a failed migration.
