[PATCH v2 1/4] Docs/RCU/rculist_nulls: Fix trivial coding style

[SeongJae Park]

Lookup example of non-hlist_nulls management is missing a semicolon, and
having inconsistent indentation (one line is using single space
indentation while others are using two spaces indentation).  Fix the
trivial issues.
