kunit: debugfs: Fix unchecked dereference in debugfs_print_results()
[ Upstream commit 34dfd5bb2e5507e69d9b6d6c90f546600c7a4977 ]
Move the call to kunit_suite_has_succeeded() after the check that
the kunit_suite pointer is valid.
This was found by smatch:
lib/kunit/debugfs.c:66 debugfs_print_results() warn: variable
dereferenced before check 'suite' (see line 63)
