rcu: Remove unused "cpu" parameter from rcu_report_qs_rdp()

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().
