rcu: Adjust FQS offline checks for exact online-CPU detection

Commit 7ec99de36f40 ("rcu: Provide exact CPU-online tracking for RCU"),
as its title suggests, got rid of RCU's remaining CPU-hotplug timing
guesswork.  This commit therefore removes the one-jiffy kludge that was
used to paper over this guesswork.
