[PATCH bpf-next 2/2] bpf, docs: Fix __uninit kfunc doc section

[David Vernet <void@manifault.com>]

In commit d96d937d7c5c ("bpf: Add __uninit kfunc annotation"), the
__uninit kfunc annotation was documented in kfuncs.rst. You have to
fully underline a section in rst, or the build will issue a warning that
the title underline is too short:

./Documentation/bpf/kfuncs.rst:104: WARNING: Title underline too short.

2.2.2 __uninit Annotation
--------------------

This patch fixes that title underline.
