Merge branch 'tcp-a-couple-of-fixes'

Paolo Abeni says:

====================
tcp: a couple of fixes

This series includes a couple of follow-up for the recent tcp receiver
changes, addressing issues outlined by the nipa CI and the mptcp
self-tests.

Note that despite the affected self-tests where MPTCP ones, the issues
are really in the TCP code, see patch 1 for the details.
