message: Fix for KMP_AFFINITY=respect with multiple processor groups
  An assert() was being tripped when KMP_AFFINITY=respect + Multiple Processor
  Groups. Let __kmp_affinity_create_proc_group_map() function be able to create
  address2os object which contains a single group by deleting restriction that
  process affinity mask must span multiple groups.
