[PATCH] dma-mapping: fix the kerneldoc for dma_map_sgtable()

[Logan Gunthorpe <logang@deltatee.com>]

htmldocs began producing the following warnings:

  kernel/dma/mapping.c:256: WARNING: Definition list ends without a
             blank line; unexpected unindent.
  kernel/dma/mapping.c:257: WARNING: Bullet list ends without a blank
             line; unexpected unindent.

Reformatting the list without hyphens fixes the warnings and produces
both a readable text and HTML output.

Fixes: fffe3cc8c219 ("dma-mapping: allow map_sg() ops to return negative error code")
