Subject: [PATCH bpf-next] Documentation: bpf: escape underscore in BPF type name prefix

Sphinx reported unknown target warning:

Documentation/bpf/bpf_design_QA.rst:329: WARNING: Unknown target name: "bpf".

The warning is caused by BPF type name prefix ("bpf_") which is written
without escaping the trailing underscore.

Escape the underscore to fix the warning. While at it, wrap the
containing paragraph in less than 80 characters.

Fixes: 9805af8d8a5b17 ("bpf: Document UAPI details for special BPF types")
