mlxsw: spectrum: Add missing packet traps
Add the following traps: 1) MTU Error: Trap packets whose size is bigger than the egress RIF's MTU. If DF bit isn't set, traffic will continue to be routed in slow path. 2) TTL Error: Trap packets whose TTL expired. This allows traceroute to work properly. 3) OSPF packets.
