    dirvote: Free vote commits in the dirauth module
    
    In order to make sr_commit_free() only used by the dirauth module, this
    commits moves the commits free from a vote object into the dirvote.c file
    which is now only for the module.
    
    The function does nothing if the module is disabled.
