[PATCH tip/core/rcu 12/52] rcu: Remove rsp parameter from print_cpu_stall()

[Paul E. McKenney]

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
print_cpu_stall().
