Subject[PATCH 5.4 70/71] perf test bpf: Free obj_buf
Date
From: Riccardo Mancini <rickyman7@gmail.com>

commit 937654ce497fb6e977a8c52baee5f7d9616302d9 upstream.

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.
