Subject: [PATCH for bpf-next] 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.

Signed-off-by: Lukas Bulwahn <lukas.bulwahn@...il.com>

applies cleanly on next-20210118

Brendan, please ack.

Alexei, please pick this minor cleanup patch on your bpf-next.
