s390/dasd: Fix a precision vs width bug in dasd_feature_list()

The "len" variable is the length of the option up to the next option or to the end of the string which ever first. We want to print the invalid option so we want precision "%.*s" but the format is width "%*s" so it prints up to the end of the string.

Thanks for the patch. I tested it and it works as expected. Will integrate it through the s390 tree.
