airo: Fix read overflows sending packets
commit 11e7a91994c29da96d847f676be023da6a2c1359 upstream.
The problem is that we always copy a minimum of ETH_ZLEN (60) bytes from
skb->data even when skb->len is less than ETH_ZLEN so it leads to a read
overflow.
The fix is to pad skb->data to at least ETH_ZLEN bytes.
