[PULL 1/5] qapi: Improve error message for description following section

[Markus Armbruster]

The error message is bad when the section is untagged.  For instance,
test case doc-interleaved-section produces "'@foobar:' can't follow
'Note' section", which is okay, but if we drop the "Note:" tag, we get
"'@foobar:' can't follow 'None' section, which is bad.

Change the error message to "description of '@foobar:' follows a
section".
