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.
