NETVIRT-1023 - OptimisticLockFailedException: infrautils.jobcoordinator-impl

https://jira.opendaylight.org/browse/NETVIRT-1023

Looks like my patch below introduced a new exception.
 https://git.opendaylight.org/gerrit/#/c/65726/

Looks like only the TZ should be deleted, which will also delete
the VTEP. So, just delete the TZ.

Note: This exception only showed up in CSIT runs, did not see
any exceptions in local testing.
