Fabio M. De Francesco 1d61261bfe swiotlb: replace kmap_atomic() with memcpy_{from,to}_page() ...

The use of kmap_atomic() is being deprecated in favor of
kmap_local_page(), which can also be used in atomic context (including
interrupts).

Replace kmap_atomic() with kmap_local_page(). Instead of open coding
mapping, memcpy(), and un-mapping, use the memcpy_{from,to}_page() helper.
