zebra: dup detected mac avoid update to bgpd

Browse Source 
When a MAC is detected duplicate on a local
learn event (with freeze action),
do not send update to bgp to advertise into
evpn control plane.

With evpn mh, inform_client flag is set and
sends notification to bgp albeit dup detect
is set.

Check mac are detected as duplicate before
setting inform_client to true.

Ticket:CM-29817

Upon local learn MAC detected as duplica
