bpf, s390: fix potential memleak when later bpf_jit_prog fails
If we would ever fail in the bpf_jit_prog() pass that writes the actual insns to the image after we got header via bpf_jit_binary_alloc() then we also need to make sure to free it through bpf_jit_binary_free() again when bailing out. Given we had prior bpf_jit_prog() passes to initially probe for clobbered registers, program size and to fill in addrs arrray for jump targets, this is more of a theoretical one, but at least make sure this doesn't break with future changes.
