David Hildenbrand a16c46c240 dma-remap: drop nth_page() in dma_common_contiguous_remap()

dma_common_contiguous_remap() is used to remap an "allocated contiguous
region".  Within a single allocation, there is no need to use nth_page()
anymore.

Neither the buddy, nor hugetlb, nor CMA will hand out problematic page
ranges.
