    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.
