selftests: mptcp: join: correctly check for no RST
commit b134a5805455d1886662a6516c965cdb9df9fbcc upstream.
The commit mentioned below was more tolerant with the number of RST seen
during a test because in some uncontrollable situations, multiple RST
can be generated.
But it was not taking into account the case where no RST are expected:
this validation was then no longer reporting issues for the 0 RST case
because it is not possible to have less than 0 RST in the counter. This
patch fixes the issue by adding a specific condition.
Fixes: 6bf41020b72b ("selftests: mptcp: update and extend fastclose test-cases")
