Fix problem with detecting wheter im processes has shutdown cleanly

  Fix problem with checking that all im processes has shutdown cleanly
  When it was detected that one of "im mysqlds" didn't shutdown, last was called to break the loop, but it only broke the inner loop.
  Remove the while(0) loop and make this easier by setting $clean_shutdown to 0 if any such problem is detected.
