    libports: fix the thread counts in case the thread creation fails
    
    Previously the number of total threads and the number of unused
    threads was wrong if at one point the creation of a thread failed. Fix
    this by decrementing both counters that were previously optimistically
    incremented. Adjust the comment accordingly.
    
    * libports/manage-multithread.c (ports_manage_port_operations_multithread):
      Fix the thread counts in case the thread creation fails.
