Subject: [PATCH] lib/scatterlist.c: fix kunmap() argument in sg_miter_stop()

kunmap() takes as argument the struct page that orginally got kmap()'d,
however the sg_miter_stop() function passed it the kernel virtual address
instead, resulting in weird stuff.

Somehow I ended up fixing this bug by accident while looking for a bug in
the same area.
