From: Uriel Guajardo <urielguajardo@xxxxxxxxxx>
Currently, if the kernel is configured incorrectly or if it crashes before any
kunit tests are run, kunit finishes without error, reporting
that 0 test cases were run.
To fix this, an error is shown when the tap header is not found, which
indicates that kunit was not able to run at all.
