Fix false positive if cppcheck doesn't give a false positive

da46fdac "tcp: Suppress knownConditionTrueFalse cppcheck false positive"
introduced a suppression to work around a cppcheck bug causing a false
positive warning.  However, the suppression will itself cause a spurious
unmatchedSuppression warning if used with a version of cppcheck from before
the bug was introduced.  That includes the packaged version of cppcheck in
Fedora.

Suppress the unmatchedSuppression as well.
