mptcp: sockopt: increase seq in mptcp_setsockopt_all_sf
mptcp_setsockopt_all_sf() was missing a call to sockopt_seq_inc(). This
is required not to cause missing synchronization for newer subflows
created later on.
This helper is called each time a socket option is set on subflows, and
future ones will need to inherit this option after their creation.
Fixes: 51c5fd09e1b4 ("mptcp: add TCP_MAXSEG sockopt support")
