selftests/resctrl: Allow ->setup() to return errors

Browse Source 
resctrl_val() assumes ->setup() always returns either 0 to continue
tests or < 0 in case of the normal termination of tests after x runs.
The latter overlaps with normal error returns.

Define END_OF_TESTS (=1) to differentiate the normal termination of
tests and return errors as negative values. Alter callers of ->setup()
to handle errors properly.

Fixes: ecdbb911f2 ("selftests/resctrl: Add MBM test")
