sunvnet: Remove irqsave/irqrestore on vio.lock
After the NAPIfication of sunvnet, we no longer need to synchronize by doing irqsave/restore on vio.lock in the I/O fastpath. NAPI ->poll() is non-reentrant, so all RX processing occurs strictly in a serialized environment. TX reclaim is done in NAPI context, so the netif_tx_lock can be used to serialize critical sections between Tx and Rx paths.
