[OpenMP] Fix for nested proc_bind affinity bug

Using proc_bind clause on a nested #pragma omp parallel region
with KMP_AFFINITY set causes an assertion error. This assertion occurs because
the place-partition-var is not properly initialized in the nested master threads.
Trying to get an intuitive result with KMP_AFFINITY + proc_bind is difficult
because of how the KMP_AFFINITY gtid-to-place mapping occurs. This
patch creates an initial place list no matter what affinity mechanism is used.
For KMP_AFFINITY, the place-partition-var is initialized to all the places.
