[PATCH] sky2: kfree_skb_any needed 

It is possible for the sky2 driver NAPI poll routine to be called with
IRQ's disabled if netpoll is trying to make space in the tx queue. This
is an obscure path, but if it happens, the kfree_skb needs to happen
via softirq. Calling kfree_skb with IRQ's disabled is a not allowed.
