  Fix segfault when reloading chan_misdn.
  
  If more ports were specified than configured in misdn.conf a reload would crash
  asterisk. The problem was the unconfigured port was using data from the
  previously configured port. When the data for an unconfigured port was freed a
  crash would result from the double free.
