Subject: [PATCH 2/3] Documentation: bpf: Add missing line break separator in node_data struct code block

From: Bagas Sanjaya <[email-masked]>
Date: Wed, 15 Feb 2023 19:32:52 +0700

Stephen Rothwell reported htmldocs warning when merging bpf-next tree,
which was the same warning as reported by kernel test robot:

Documentation/bpf/graph_ds_impl.rst:62: ERROR: Error in "code-block" directive:
maximum 1 argument(s) allowed, 12 supplied.

The error is due to Sphinx confuses node_data struct declaration with
code-block directive option.

Fix the warning by separating the code-block marker with node_data struct
declaration.
