via-velocity: Correct 64-byte alignment for rx buffers

Browse source

(From the VIA driver). The current code does not guarantee 64-byte
alignment since it simply does

        int add = skb->data & 63;

        skb->data += add;

(via skb_reserve). So for example, if the skb->data address would be
0x10, this would result in 32-byte alignment (0x10 + 0x10).

Correct by adding

        64 - (skb->data & 63)

instead.
