    mark_freq: fixed 100% CPU usage when mark_freq() is changed to 0 during a SIGHUP
    
    If mark_freq() is set to 0 from a non-zero value and syslog-ng receives
    a SIGHUP, it started spinning and emitting MARK messages like crazy.
    
    This patch reinitializes the next_mark_target variable on SIGHUP which causes
    it to behave normally.
