  Don't crash or deadlock on module unload
  
  We can't hold the lock while pthread_join is called since aji_log_hook will
  attempt to lock from the other therad. We reorder the pthread_join and
  ast_aji_disconnect so that we don't do an SSL_read() while SSL_shutdown is
  running, causing a crash.
