[PATCH] kunit: fix -Wunused-function warning for __kunit_fail_current_test

[PATCH] kunit: fix -Wunused-function warning for __kunit_fail_current_test

[Daniel Latypov]

When CONFIG_KUNIT is not enabled, __kunit_fail_current_test() an empty
static function.

But GCC complains about unused static functions, *unless* they're static inline.
So add inline to make GCC happy.

Signed-off-by comes after Fixes. Also good to add Reported-by for 
Stephen acknowledging the reporter.

I will fix this up when I apply - for future reference.
