The virtio-pmem documentation has some minor style issues we hadn't
noticed since we weren't rendering it in our docs:
* Sphinx doesn't complain about overlong title-underlining the
way it complains about too-short underlining, but it looks odd;
make the underlines of section headers the right length
* Indent of paragraphs makes them render as blockquotes;
remove the indent so they just render as normal text
* Leading 'o' isn't rst markup, so it just renders as a literal
"o"; reformat as a subsection heading instead
* "QEMU" in the document title and section headings are a bit
odd and unnecessary since this is the QEMU manual; delete
or rephrase them
* There's no need to specify what QEMU version the device first
appeared in.
