rcu: Add missing __releases() annotation 



Sparse reports a warning at rcu_print_task_stall():

"warning: context imbalance in rcu_print_task_stall - unexpected unlock"

The root cause is a missing annotation on rcu_print_task_stall().

This commit therefore adds the missing __releases(rnp->lock) annotation.
