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.
