[PATCH] python/osmo-python-tests[master]: cosmetic: early exit instead of if-cascade

[Neels Hofmeyr]

cosmetic: early exit instead of if-cascade

It appears that during some error conditions, the socket will not be in the tcp
socket debug tracking list, and on top of an exception this barfs as well.
Let's not care about the tcp debug list and avoid confusing error messages.
