dma-mapping: fix the kerneldoc for dma_map_sgtable()
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")
