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: fffe3cc8c2 ("dma-mapping: allow map_sg() ops to return negative error code")

*
* -EINVAL - An invalid argument, unaligned access or other error
* in usage. Will not succeed if retried.
* -ENOMEM - Insufficient resources (like memory or IOVA space) to
* complete the mapping. Should succeed if retried later.
* -EIO - Legacy error code with an unknown meaning. eg. this is
