drivers/target: Call page_address() on page acquired with GFP_KERNEL flag

rd_allocate_sgl_table() acquires a page with alloc_pages(GFP_KERNEL, 0). Pages allocated with GFP_KERNEL cannot come from Highmem. This is why there is no need to call kmap() on them.

Therefore, use a plain page_address() on that page.
