rcu: Remove rsp parameter from rcu_print_detail_task_stall()

Browse Source 
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_print_detail_task_stall().
