[PATCH 5.4 151/215] selftests: reuseaddr_conflict: add missing new line at the end of the output

From: Jakub Kicinski <kuba@kernel.org>

commit 31974122cfdeaf56abc18d8ab740d580d9833e90 upstream.

The netdev CI runs in a VM and captures serial, so stdout and
stderr get combined. Because there's a missing new line in
stderr the test ends up corrupting KTAP:

# Successok 1 selftests: net: reuseaddr_conflict

which should have been:

# Success
ok 1 selftests: net: reuseaddr_conflict

Fixes: 422d8dc6fd3a ("selftest: add a reuseaddr test")
