As noticed by Russell King, the last argument of mvpp2_rx_{pkts,time}_coal_set() is useless, since the packet/time coalescing value is already stored in the 'struct mvpp2_rx_queue *' passed as argument to these functions. So passing the packet/time value as an additional argument, and setting them again in the mvpp2_rx_queue structure is useles. This commit therefore gets rid of this additional argument, assuming the caller has assigned the appropriate value to rxq->pkts_coal or rxq->time_coal before calling the respective functions.
