tcp: consistently disable header prediction for mptcp
commit 71158bb1f2d2da61385c58fc1114e1a1c19984ba upstream.
The MPTCP receive path is hooked only into the TCP slow-path.
The DSS presence allows plain MPTCP traffic to hit that
consistently.
Since commit e1ff9e82e2ea ("net: mptcp: improve fallback to TCP"),
when an MPTCP socket falls back to TCP, it can hit the TCP receive
fast-path, and delay or stop triggering the event notification.
Address the issue explicitly disabling the header prediction
for MPTCP sockets.
Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/200
Fixes: e1ff9e82e2ea ("net: mptcp: improve fallback to TCP")
