[PATCH 1/2] blk-mq-dma: fix kernel-doc for integrity DMA iterators

blk_rq_integrity_dma_map_iter_next() documents a @state parameter it
has never had.  It takes (req, dma_dev, iter), as declared in
include/linux/blk-integrity.h, so scripts/kernel-doc reports an "Excess
function parameter 'state' description" warning at
block/blk-mq-dma.c:379.

The wrapped summary lines of both integrity helpers also indent with
tabs directly after "* ", which checkpatch flags as:

  block/blk-mq-dma.c:320: WARNING: please, no space before tabs
  block/blk-mq-dma.c:361: WARNING: please, no space before tabs

Drop the stale parameter description and use spaces for the alignment;
the rendered output is unchanged.  No functional change.

Both issues were found by running scripts/kernel-doc and
scripts/checkpatch.pl over block/, and verified against the prototype
in include/linux/blk-integrity.h.
