Matthieu Baerts (NGI0) 14e22b43df selftests: mptcp: connect: catch IO errors on listen side
IO errors were correctly printed to stderr, and propagated up to the
main loop for the server side, but the returned value was ignored. As a
consequence, the program for the listener side was no longer exiting
with an error code in case of IO issues.

Because of that, some issues might not have been seen. But very likely,
most issues either had an effect on the client side, or the file
transfer was not the expected one, e.g. the connection got reset before
the end. Still, it is better to fix this.

The main consequence of this issue is the error that was reported by the
selftests: the received and sent files were different, and the MIB
counters were not printed. Also, when such errors happened during the
'disconnect' tests, the program tried to continue until the timeout.

Now when an IO error is detected, the program exits directly with an
error.
