Remove the variable sz because it's invariantly == 0,

along with the dead code testing whether it's positive.
Reported by Ulrich Spoerlein <uqs@spoerlein.net>,
found by Coverity Scan CID 975717.

While here, remove the now unused **params array as well,
which Coverity apparently missed, at least it wasn't reported...
