skb_find_text ignores to argument

skb_find_text takes a "to" argument which is supposed to limit how far into the skb it will search for the given text. At present, it seems to ignore that argument on the first skb, and instead return a match even if the text occurs beyond the limit.

Patch below fixes this, after adjusting for the "from" starting point. This consequently fixes the netfilter string match's "--to" handling, which currently is broken.
