hugetlb: fix clear_user_highpage arguments
The virtual address space argument of clear_user_highpage is supposed to be the virtual address where the page being cleared will eventually be mapped. This allows architectures with virtually indexed caches a few clever tricks. That sort of trick falls over in painful ways if the virtual address argument is wrong.
