net: libwx: fix multicast packets received count
commit 2b30a3d1ec2538a1fd363fde746b9fe1d38abc77 upstream.
Multicast good packets received by PF rings that pass ethternet MAC
address filtering are counted for rtnl_link_stats64.multicast. The
counter is not cleared on read. Fix the duplicate counting on updating
statistics.
