Lorenz Bauer bb0de3131f bpf: sockmap: Require attach_bpf_fd when detaching a program
The sockmap code currently ignores the value of attach_bpf_fd when
detaching a program. This is contrary to the usual behaviour of
checking that attach_bpf_fd represents the currently attached
program.

Ensure that attach_bpf_fd is indeed the currently attached
program. It turns out that all sockmap selftests already do this,
which indicates that this is unlikely to cause breakage.

Fixes: 604326b41a ("bpf, sockmap: convert to generic sk_msg interface")
