While I'm looking into how to account standard tx counters on XDP tx
processing, I found several bugs around XDP tx and napi_tx.

Patch1: Fix oops on error path. Patch2 depends on this.
Patch2: Fix memory corruption on freeing xdp_frames with napi_tx enabled.
Patch3: Minor fix patch5 depends on.
Patch4: Fix memory corruption on processing xdp_frames when XDP is disabled.
  Also patch5 depends on this.
Patch5: Fix memory corruption on processing xdp_frames while XDP is being
  disabled.
Patch6: Minor fix patch7 depends on.
Patch7: Fix memory corruption on freeing sk_buff or xdp_frames when a normal
  queue is reused for XDP and vise versa.

v2:
- patch5: Make rcu_assign_pointer/synchronize_net conditional instead of
          _virtnet_set_queues.
- patch7: Use napi_consume_skb() instead of dev_consume_skb_any()
