sscanf: don't ignore field widths for numeric conversions
This is another step towards better standard conformance. Rather than adding a local buffer to store the specified portion of the string (with the need to enforce an arbitrary maximum supported width to limit the buffer size), do a maximum width conversion and then drop as much of it as is necessary to meet the caller's request. Also fail on negative field widths. Uses the deprecated simple_strto*() functions because kstrtoXX() fail on non-zero terminated strings.
