We interpret port values as signed int (convert them from char *), so if a negative value is provided in network disk's configuration, we accept it as valid, however there's an 'unknown cause' error raised later. This error is only accidental because we return the port value in the return code. This patch adds just a minor tweak to the already existing check so we reject negative values the same way as we reject non-numerical strings.
