swiotlb: search and replace "int dir" with "enum dma_data_direction dir" 

.. to catch anybody doing something funky.

See "swiotlb: swiotlb: add swiotlb_tbl_map_single library function" for
full description of patchset.

[v2: swiotlb_sync_single_range_* no more - removed usage]
[v3: enum dma_data_direction direction -> enum dma_data_direction dir]
