[PATCH 2/2] blk-mq-dma: fix typo in DMA iterator kernel-doc

[Bryan Boquel <boquelbryan6@gmail.com>]

blk_rq_dma_map_iter_start() and blk_rq_dma_map_iter_next() both
document their return value as "%true ft it did map a segment", where
"ft" should read "if".  The two integrity variants further down spell
it correctly.

No functional change.
