Hi, is there some setting that would allow pthread_setaffinity_np() to
succeed for non-root users, i.e. some form of RBAC?

Not that I know of. There was a discussion to introduce a sysctl(7),
but never got implemented actually (here's a quick patch).

Is that patch right?  It appears to allow the variable to be set
regardless of the kernel security level.

Should not? I took the same logic as the one allowing usermounts. It's a matter of policy though.
