qapi/parser: fix comment parsing immediately following a doc block

If a comment immediately follows a doc block, the parser doesn't ignore
that token appropriately. Fix that.

e.g.

> ##
> # = Hello World!
> ##
>
> # I'm a comment!

will break the parser, because it does not properly ignore the comment
token if it immediately follows a doc block.
