Subject: 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.
