Maybe there's a better way, but you could run this on the two chassis
that are involved:
ovs-vsctl --format table --columns=name,external-ids list Interface
And look for for port UUID from the log message, it should show up
with "iface-id=" on both chassis (but should appear on only one).
Once you figure out which one is wrong, do:
ovs-vsctl remove Interface <port-name> external_ids iface-id=<interface-id>
If you're running a recent version of ovs master, you might just need
the fix listed below which was committed yesterday (maybe you don't have
a duplicate port binding after all):

ovn-controller: Log chassis claiming lport only when changes occur.
With recent OVN commits, the logic for a chassis to claim
or release a logical port was consolidated. This is a
good thing. However, there was a logic change that
resulted in VLOG_INFO being generated every time on the
ovn-controller. This patch changes the logic so that
VLOG_INFO is only generated when there is a change, for
example when the chassis claims an lport the first time.
