bridge: Reorder neighbor suppression check when flooding
The bridge does not flood ARP / NS packets for which a reply was sent to
bridge ports that have neighbor suppression enabled.
Subsequent patches are going to add per-{Port, VLAN} neighbor
suppression, which is going to make it more expensive to check whether
neighbor suppression is enabled since a VLAN lookup will be required.
Therefore, instead of unnecessarily performing this lookup for every
packet, only perform it for ARP / NS packets for which a reply was sent.
