driver_ndis: Add PAE group address to the multicast address

Browse Source 
This is done with wired interfaces to fix IEEE 802.1X authentication
when the authenticator uses the group address (which should be happening
with wired Ethernet authentication).

This allows wpa_supplicant to complete wired authentication successfully
on Vista with a NDIS 6 driver, but the change is likely needed for
Windows XP, too.
