selftests/resctrl: Don't leak buffer in fill_cache()
[ Upstream commit2d320b1029
] The error path in fill_cache() does return before the allocated buffer is freed leaking the buffer. The leak was introduced when fill_cache_read() started to return errors in commitc7b607fa93
("selftests/resctrl: Fix null pointer dereference on open failed"), before that both fill functions always returned 0. Move free() earlier to prevent the mem leak. Fixes:c7b607fa93
