The OMP_PROC_BIND=spread strategy fails to assign the master thread the correct place partition after the first parallel region. Other threads in the hot team will remember their place_partition, but the master's place partition is restored to what it was before entering the parallel region. So when the hot team is used for subsequent parallel regions, the master has lost this info. This fix calls __kmp_partition_places to update only the master thread's place partition in the spread case when there are no other changes to the hot team.
