tests: skip the rest of test_mnt_id after getting any error

Browse Source 
This mainly gets around a kernel bug making it possible to
have non-existent paths in /proc/self/mountinfo, but it should also
prevent flaky failures that can happen if something changes immediately
after or during reading /proc/self/mountinfo.

Closes https://github.com/systemd/systemd/issues/8286.
