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")
