docs, bpf: Add minimal markup to address doc warning
Commit 91c960b00566 ("bpf: Rename BPF_XADD and prepare to encode other
atomics in .imm") modified the BPF documentation, but missed some ReST
markup.
Hence, make htmldocs warns on Documentation/networking/filter.rst:1053:
WARNING: Inline emphasis start-string without end-string.
Add some minimal markup to address this warning.
Fixes: 91c960b00566 ("bpf: Rename BPF_XADD and prepare to encode other atomics in .imm")
