tests: Ignore no tunnel port error on vswitch stop.

The test failure occurs quite consistently (~50% of the runs) when using
a musl static build. It always happens if I add `sync` or `sleep` before
vswitchd shutdown. The warning message can be seen in the
retained vswitchd log (-d) even when the test case passes.

I believe a race condition between vswitchd flushing the log to disc and
the test code reading from the log file explains why the test case
doesn't fail consistently.
