tc: act_bpf: fix memory leak
prog->bpf_ops is populated when act_bpf is used with classic BPF and prog->bpf_name is optionally used with extended BPF. Fix memory leak when act_bpf is released. Fixes: d23b8ad8ab23 ("tc: add BPF based action") Fixes: a8cb5f556b56 ("act_bpf: add initial eBPF support for actions") Acked-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Alexei Starovoitov <ast@plumgrid.com> Signed-off-by: David S. Miller <davem@davemloft.net>
