netdev-dpdk: add support for rx_multicast_packets counter

This patch enables already implemented ifInMulticastPkts counter in sFlow for
DPDK interfaces. Metric is retrieved from DPDK by using extended statistic API
and stored in 'multicast' member of netdev_stats structure, which represents
number of incoming packets that were addressed to a multicast address.
