swiotlb: use swiotlb_sync_single instead of duplicating code

Right now both swiotlb_sync_single_range and swiotlb_sync_sg
were duplicating the code in swiotlb_sync_single.  Just call it
instead.  Also rearrange the sync_single code for readability.

Note that the swiotlb_sync_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.
