net: r8169: Disable multicast filter for RTL8168H and RTL8107E



[ Upstream commit efa5f1311c4998e9e6317c52bc5ee93b3a0f36df ]

RTL8168H and RTL8107E ethernet adapters erroneously filter unicast
eapol packets unless allmulti is enabled. These devices correspond to
RTL_GIGA_MAC_VER_46 and VER_48. Add an exception for VER_46 and VER_48
in the same way that VER_35 has an exception.
