rcu: Remove rsp parameter from rcu_gp_slow()
There now is only one rcu_state structure in a given build of the Linux kernel, so there is no need to pass it as a parameter to RCU's functions. This commit therefore removes the rsp parameter from rcu_gp_slow(). Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
