[PATCH] rcu: Make it stop complaining about docbook function-header comment

[Byungchul Park]

Running "make htmldocs" complains about the docbook function-header
comment. It wants the "irq" parameter described which wasn't done by
a commit 5e5ea52645b197 (rcu: Refactor rcu_{nmi,irq}_{enter,exit}()).
So add its description of the parameter to the comment.
