docs/bpf: Fix "file doesn't exist" warnings in {llvm_reloc,btf}.rst

scripts/documentation-file-ref-check reports warnings for (valid) cross-links of form: :ref:`Documentation/bpf/btf <BTF_Ext_Section>` Adding extension to the file name helps to avoid the warning, e.g: :ref:`Documentation/bpf/btf.rst <BTF_Ext_Section>` Fixes: be4033d ("docs/bpf: Add description for CO-RE relocations") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Eduard Zingerman <eddyz87@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Jiri Olsa <jolsa@kernel.org> Closes: https://lore.kernel.org/oe-kbuild-all/202309010804.G3MpXo59-lkp@intel.com Link: https://lore.kernel.org/bpf/20230901125935.487972-1-eddyz87@gmail.com
