Public bug reported:

TC shouldn't raise an exception when deleting qdisc if device doesn't
exist.

When Linux Bridge agent deletes a port or detect a port was deleted, QoS
extension is informed to clean any traffic shapping in this port by
deleting the qdisc. If the port was already deleted, TC will raise an
exception:

ProcessExecutionError: Exit code: 1; Stdin: ; Stdout: ; Stderr: Cannot
find device "tape0f6e79a-0b"

Logs: http://logs.openstack.org/85/473685/3/check/gate-tempest-dsvm-
neutron-scenario-linuxbridge-ubuntu-xenial-
nv/427484d/logs/screen-q-agt.txt.gz?level=WARNING#_Jun_13_07_36_14_943304

In this case, TC should catch silently this exception.
