b44: fix IFF_ALLMULTI handling of CAM slots
If you set the IFF_ALLMULTI flag on a b44 device, or if you join more than
B44_MCAST_TABLE_SIZE multicast groups, the device will stop receiving unicast
messages. This is because the __b44_set_mac_addr call sets the zeroth CAM
entry to the MAC address of the device, and then the loop at line 1722
proceeds to overwrite it unless the value of i is set by the __b44_load_mcast
call. However, when IFF_ALLMULTI is set, that call is bypassed, leaving i set
to zero.
Fixed by starting the loop at 1 to make it skip the CAM entry for the MAC
address.
