Subject: [PATCH] qemuBackupDiskDataCleanupOne: Don't exit early when the job
has started
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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.
