Jinjie Ruan 71edfc9511 kunit: Fix possible memory leak in kunit_filter_suites() ...

[ Upstream commit 24de14c98b37ea40a7e493dfd0d93b400b6efbca ]

If the outer layer for loop is iterated more than once and it fails not
in the first iteration, the filtered_suite and filtered_suite->test_cases
allocated in the last kunit_filter_attr_tests() in last inner for loop
is leaked.

So add a new free_filtered_suite err label and free the filtered_suite
and filtered_suite->test_cases so far. And change kmalloc_array of copy
to kcalloc to Clear the copy to make the kfree safe.
