BACKPORT: rcu: Remove __read_mostly annotations from rcu_scheduler_active externs

Browse Source 
Remove the __read_mostly attributes from the rcu_scheduler_active
extern declarations, because these attributes are ignored for
prototypes and we'd have to include the full <linux/cache.h> header
to gain this functionally pointless attribute defined.
