[PATCH iproute2] man: fix small formatting errors

[Luca Boccassi <bluca@debian.org>]

Lintian detected the following formatting errors:

 man/man8/devlink-sb.8.gz 230: warning: macro `b' not defined
 man/man8/ip-link.8.gz 1243: warning: macro `in-8' not defined
  (possibly missing space after `in')
 man/man8/tc-u32.8.gz `R' is a string (producing the registered sign),
  not a macro.
