From: Riccardo Mancini <rickyman7@gmail.com>
[ Upstream commit 937654ce497fb6e977a8c52baee5f7d9616302d9 ]
ASan reports some memory leaks when running:
# perf test "42: BPF filter"
The first of these leaks is caused by obj_buf never being deallocated in __test__bpf.
This patch adds the missing free.
