Eric Dumazet 8776c4ef3a inet: add dst4_mtu() and dst6_mtu() helpers
With CONFIG_MITIGATION_RETPOLINE=y dst_mtu() is a bit fat,
because it is generic.

Indeed, clang does not always inline it.

Add dst4_mtu() and dst6_mtu() helpers for callers that
expect either ipv4_mtu() or ip6_mtu() to be called.

These helpers are always inlined.
