qapi/block-core.json: Fix nbd-server-start docs
Commit
eed8b6917832 added some new text to the nbd-server-start
documentation in the wrong place. Since this is after the 'Returns:'
line it's parsed as if it were part of the documentation of the
"Returns:' information. Move it up to join the rest of the
"documentation of the type as a whole" doc text.
This doesn't look odd in the current HTML rendering, but the
new QAPI-to-rST handling will complain about the indent level
of the lines not matching up with the 'Returns:' line.
