That patch should probably be reverted. It was an attempt to fix bug 19982, but it does not: Wine uses the posix API to create threads, and it should use the posix API to set the affinity too.
No, the Posix API only works inside the process, from the wineserver using the syscall is correct. There must be some other problem here.
