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.
