docs: Don't define duplicate label in qemu-block-drivers.rst.inc

Browse source 
Sphinx requires that labels within documents are unique across the
whole manual.  This is because the "create a hyperlink" directive
specifies only the name of the label, not a filename+label.  Some
Sphinx versions will warn about duplicate labels, but even if there
is no warning there is still an ambiguity and no guarantee that the
hyperlink will be created to the right target.

For QEMU this is awkward, because we have various .rst.inc fragments
which we include into multiple .rst files.  If you define a label in
the .rst.inc file then it will be a duplicate label.  We have mostly
worked around this by not putting labels into those .rst.inc files,
or by adding "insert a label" functionality into the hxtool extension
(see commit 1eeb432a95 "doc/sphinx/hxtool.py: add optional label
argument to SRST directive").

Unfortunately in commit 7f6314427e ("docs/devel: add a codebase
section") we accidentally added a duplicate label, because not all
Sphinx versions warn about the mistake.

In this case the link was only from the developer docs codebase
summary, so as the simplest fix for the stable branch, we drop
the link entirely.
