Subject: kunit: Fix the wrong kfree of copy for kunit_filter_suites()

[ Upstream commit e44679515a7b803cf0143dc9de3d2ecbe907f939 ]

If the outer layer for loop is iterated more than once and it fails not
in the first iteration, the copy pointer has been moved. So it should free
the original copy's backup copy_start.
