  -----------
  [OpenMP] Fix distributed barrier hang for OMP_WAIT_POLICY=passive (#83058)

The resume thread logic inside __kmp_free_team() is faulty. Only
checking b_go for sleep status doesn't wake up distributed barrier.
Change to generic check for th_sleep_loc and calling
__kmp_null_resume_wrapper().

Fixes: #80664
