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

[Sumitra Sharma]

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.
