docs/core-api: swiotlb: fix typos

Browse Source 
Correct references to swiotlb_tbl_map_single() and
swiotlb_tbl_unmap_single() in the documentation for swiotlb.

Fix two small typos that went unnoticed in commit c93f261dfc
("Documentation/core-api: add swiotlb documentation"):
swiotlb_tlb_map_single --> swiotlb_tbl_map_single
swiotbl_tlb_unmap_single --> swiotlb_tbl_unmap_single
