====================
mptcp: More fixes for 6.1

Patch 1 makes sure data received after a close will still be processed
and acked as exepected. This is a regression for a commit introduced
in v5.11.

Patch 2 fixes a kernel deadlock found when working on validating TFO
with a listener MPTCP socket. This is not directly linked to TFO but
it is easier to reproduce the issue with it. This fixes a bug introduced
by a commit from v6.0.
