Michal Luczaj a25566084e bpf, sockmap: Annotate af_unix sock:: Sk_state data-races ...

sock_map_sk_state_allowed() and sock_map_redirect_allowed() read af_unix
socket sk_state locklessly.

Use READ_ONCE(). Note that for sock_map_redirect_allowed() change affects
not only af_unix, but all non-TCP sockets (UDP, af_vsock).
