In commit 0ea9d5e3e0e03a63b11392f5613378977dae7eca ("xfrm: introduce
helper for safe determination of mtu") I switched the determination of
ipv4 mtus from dst_mtu to ip_skb_dst_mtu. This was an error because in
case of IP_PMTUDISC_PROBE we fall back to the interface mtu, which is
never correct for ipv4 ipsec.

This patch partly reverts 0ea9d5e3e0e03a63b11392f5613378977dae7eca
("xfrm: introduce helper for safe determination of mtu").
