Eric noted a probable shinfo->nr_frags corruption, which indeed
occurs.
The root cause is a buggy MPTCP option len computation in some
circumstances: the ADD_ADDR option should be mutually exclusive
with DSS since the blamed commit.
Still, mptcp_established_options_add_addr() tries to set the
relevant info in mptcp_out_options, if
