If you want to exit the subtest you really have to handle the return
values yourself, report the error, and return from the test function.

The question is which status to report. The TBROK status means that test
has failed setup phase and there is no point to continue, so this
probably should map to tst_res TWARN "...".

Another solution would be splitting the test into three seprate tests
so that we can use ROD.
