When looking for PUs inside R_MAXSDL rads, some AIX 6.1 releases
return one first rad without any PU.
AIX 6.1 00F63F144C00 does (on quad-power7).
AIX 6.1 00CBAAC24C00 doesn't (on 16x power6).
So we can't assume rad #x contains PU #x. But we already have the right
code to fill the cpuset from the rad, so use that to obtain the PU os_index
as well.
Cannot be used to obtain NUMA node os_index since there's no way to directly
retrieve NUMA nodes from rads (mempools seem unrelated). Just keep using #rad
for NUMA nodes os_index and document that convention when converting back in
set_membind().
Thanks to Hendryk Bockelmann and Erik Schnetter for helping debugging.
