Merge branch 'dev_kfree_skb'

Alexander Duyck says:

====================
Clean-up some bits related to netpoll

This patch set cleans up some minor items related to netpoll.  The first
patch addresses an Rx clean-up bug that is triggered due to an assumption
that napi->poll wouldn't be called with a budget of 0.  The other two
patches address dev_kfree_skb being called in the xmit path which isn't
valid since netpoll will call ndo_start_xmit with IRQs disabled.
