net: Fix -net socket parameter checks

My commit ea053add700d8abe203cd79a9ffb082aee4eabc0 broke -net socket by
overwriting an intermediate buffer in the added check_param. Fix this
by switching check_param to automatic buffer allocation and release, ie.
callers no longer have to worry about providing a scratch buffer.
