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

[ Upstream commit 38289a26e1b8a37755f3e07056ca416c1ee2a2e8 ]

Commit 6d2426b2f258 ("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.
