Fix support for dropping non-first threads in the Linux-cpuinfo code when IGNORE_THREADS is given.
Fix support for dropping non-first threads in the Linux-cpuinfo code
when IGNORE_THREADS is given.

Don't fill a nonfirst_threads_cpuset while parsing /proc/cpuinfo
since the admin_disabled_cpuset can make it wrong.
Just wait for admin_disabled cpus to be gone, and then do a loop
comparing proc_coreids and clearing the nonfirst ones.
