e1000x: Fix BPRC and MPRC

Before this change, e1000 and the common code updated BPRC and MPRC
depending on the matched filter, but e1000e and igb decided to update
those counters by deriving the packet type independently. This
inconsistency caused a multicast packet to be counted twice.

Updating BPRC and MPRC depending on are fundamentally flawed anyway as
a filter can be used for different types of packets. For example, it is
possible to filter broadcast packets with MTA.

Always determine what counters to update by inspecting the packets.
