octeontx2-af: Set proper errorcode for IPv4 checksum errors
With current config, for packets with IPv4 checksum errors, errorcode is being set to UNKNOWN. Hence added a separate errorcodes for outer and inner IPv4 checksum and changed NPC configuration accordingly. Also turn on L2 multicast address check in NPC protocol check block.
