[PATCH] ppc: fix sungem NAPI (#2)

[Benjamin Herrenschmidt <benh@kernel.crashing.org>]

Hi !

(Resent with proper signed-off line after ack from David)

The recent sungem NAPI change introduced a bug: dev_kfree_skb() is called
within the spinlock, thus triggers all sort of WARN_ON's later on down the
stack.

This patch changes it to dev_kfree_skb_any(), I hope that is fine
as we aren't really in interrupt, are we ? (I don't know in what
context NAPI polling occurs, is it a timer IRQ ?)

Ben.
