loci: fix OF 1.2+ packet-in data offset

There are two bytes of padding between the match and the packet data.

This commit introduces "extra length", which is the sum of the fixed length
parts of an object having variable offsets (after a variable length member).
The only use is for OF 1.2+ packet-in messages.
