xfrm: expose local_rxpmtu via ipv6_stubs
We cannot call this function from the core kernel unless we would force
CONFIG_IPV6=y.
Therefore expose this via ipv6_stubs so we can call it from net/xfrm
in the followup patch.
Since the call is expected to be unlikely, no extra code for the IPV6=y
case is added and we will always eat the indirection cost.
