Build Update for ovsrobot/ovs
-------------------------------------

Build: #2444
Status: Passed

Duration: 1 hr, 10 mins, and 49 secs
Commit: 5054df0 (series_168987)
Author: Dumitru Ceara
Message: ovn-controller: Fix potential segfault with "virtual" port bindings.

Even though ovn-controller tries to set port_binding->chassis to NULL
every time port_binding->virtual_parent is set to NULL for bindings of
type="virtual", there's no way to enforce that an operator doesn't
manually clear the "virtual_parent" column in the Southbound database.

In such scenario ovn-controller would crash because of trying to
dereference the NULL port_binding->virtual_parent column.

Add an extra check and release "virtual" port bindings that have
"virtual_parent" NULL.
