rcu: Eliminate second argument of rcu_process_dyntick()

At this point, the second argument to all calls to
rcu_process_dyntick() is a function of the same field of the
structure passed in as the first argument, namely, rsp->gpnum-1.
 So propagate rsp->gpnum-1 to all uses of the second argument
within rcu_process_dyntick() and then eliminate the second
argument.
