Geliang Tang 535d620ea5 mptcp: map v4 address to v6 when destroying subflow
Address family of server side mismatches with that of client side, like
in "userspace pm add & remove address" test:

    userspace_pm_add_addr $ns1 10.0.2.1 10
    userspace_pm_rm_sf $ns1 "::ffff:10.0.2.1" $SUB_ESTABLISHED

That's because on the server side, the family is set to AF_INET6 and the
v4 address is mapped in a v6 one.

This patch fixes this issue. In mptcp_pm_nl_subflow_destroy_doit(), before
checking local address family with remote address family, map an IPv4
address to an IPv6 address if the pair is a v4-mapped address.

Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/387
Fixes: 702c2f646d ("mptcp: netlink: allow userspace-driven subflow establishment")
