Let's also fix IPsec PMTU storage.  When we get an MTU update for an
xfrm_dst, it should be done to the top dst, not the bottom dst.

For example, when we get a need-to-frag message for host C behind
a our IPsec peer B, we should be updating the dst entry for C and
not B as we do now.

I've removed the boundary checks since the same checks are done
in ipv[46]/route.c already.

Applied, thanks Herbert.

Note that sometimes it is better to replace an "unnecessary as
determined by me" boundary check with a BUG() instead of
outright removal.  That way you get to test your assertion :)
