Don't drop ARP table jump during OVS rewiring

Don't drop ARP table jump during OVS rewiring

The previous OVS ARP spoofing code was dropping the rule to jump to
the ARP protection table each time it was called. This call was
unnecessary since the majority of port updates are not turning
off port security.

This patch adjusts the logic to only drop the jump rule if port-sec
is disabled or if it is a network port. The existing functional tests
ensure that connectivity works as expected.
