Subject: [PATCH net-next 02/13] selftests: mptcp: userspace pm: don't stop
 if error

No more tests were executed after a failure but it is still interesting
to get results for all the tests to better understand what's still OK
and what's not after a modification.

Now we only exit earlier if the two connections cannot be established.
