swiotlb: rename unmap_single to do_unmap_single
Previously, swiotlb_unmap_page and swiotlb_unmap_sg were
duplicating very similar code. Refactor that code into a
new unmap_single and unmap_single use do_unmap_single.
Note that the swiotlb_unmap_sg code was previously doing
a complicated comparison to determine if an addresses needed
to be unmapped where a simple is_swiotlb_buffer() call
would have sufficed.
