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

Fourth, the io_tlb_slot array keeps track of any "padding slots" allocated to

swiotlb_tbl_map_single() allocates bounce buffer space to meet alloc_align_mask

when swiotlb_tbl_unmap_single() is called with the bounce buffer address, the
alloc_align_mask value that governed the allocation, and therefore the
allocation of any padding slots, is not known. The "pad_slots" field records
the number of padding slots so that swiotlb_tbl_unmap_single() can free them.
