The "cpu" parameter to rcu_report_qs_rdp() is not used, with rdp->cpu being used instead. Furtheremore, every call to rcu_report_qs_rdp() invokes it on rdp->cpu. This commit therefore removes this unused "cpu" parameter and converts a check of rdp->cpu against smp_processor_id() to a WARN_ON_ONCE().
