From: Peter Maydell <peter.maydell@linaro.org>

Use the uniquelabel directive for the 'nbd' label in
qemu-block-drivers.rst.inc.  This avoids a complaint from some Sphinx
versions about it being a duplicate label, and means that we can
reliably ensure that the link in codebase.rst goes to the document
file that we intend (i.e.  the section of the HTML manual on disk
images, not the HTML copy of the qemu-block-drivers manpage).
