kunit: fix debugfs code to use enum kunit_status, not bool

Commit 6d2426b2 ("kunit: Support skipped tests") switched to using
`enum kunit_status` to track the result of running a test/suite since we
now have more than just pass/fail.

This callsite wasn't updated, silently converting to enum to a bool and
then back.
