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")
