The new struct flow_tnl contains an extra four bytes of padding on
64-bit machines but we currently assert that the total struct flow
is a fixed size. The size difference isn't actually a problem
because both are multiples of 4 and the build assertion is only
intended to remind people to update FLOW_WC_SEQ when new fields are
added. This changes the assertion to fix just the non-tunnel field
size.
