rcu: Merge rcu_sched_force_quiescent_state() with rcu_force_quiescent_state()
This patch merges the function rcu_force_quiescent_state() with rcu_sched_force_quiescent_state(), using the rcu_state pointer. Firstly, the rcu_sched_force_quiescent_state() function is deleted from the file kernel/rcu/tree.c. Also, the rcu_force_quiescent_state() function that was calling force_quiescent_state with the argument rcu_preempt_state pointer was deleted as well. The new function that combines the old ones uses the rcu_state pointer and is located after rcu_batches_completed_bh() in kernel/rcu/tree.c.
