datapath: Increase size of max nlattr-formatted flow to 132.
The addition of IPv6 matching increased the maximum size of a
nlattr-formatted flow. This was not properly reflected in the userspace
and kernel #defines that reserve space for the flows and could lead to
crashes. This commit increases the size uniformly to 132 bytes.
