[PATCH 4/5] qemuBackupDiskDataCleanupOne: Don't exit early when the job has started

Originally the function was cleaning up a failed job only but now
there's other stuff that needs to be cleared too.

Make only steps which clean up after a failed job depend on the
'started' field and execute the rest of the code always.

This fixes a leak of the backup job tracking object and the blockdev-add
helper data.
