TCP: Obvious Spurious Retransmissions are not always detected
In rare circumstances Spurious Retransmissions are not detected
and the SEQ analysis would instead conclude with a Fast Retransmit
or an Out-Of-Order. As Spurious Retransmissions are more certain
than the latter ones, their respective precedences are changed.
The documentation is updated accordingly. Closes #13863.
