Paul E. McKenney 02ddf26d84 rcu-tasks: Move RTGS_WAIT_CBS to beginning of rcu_tasks_kthread() loop 
[ Upstream commit 0db7c32ad3160ae06f497d48a74bd46a2a35e6bf ]

Early in debugging, it made some sense to differentiate the first
iteration from subsequent iterations, but now this just causes confusion.
This commit therefore moves the "set_tasks_gp_state(rtp, RTGS_WAIT_CBS)"
statement to the beginning of the "for" loop in rcu_tasks_kthread().
