TI Davinci EMAC : Fix Console Hang when bringing the interface down
In the NAPI poll function(emac_poll), check for netif_running() is unnecassary. In addition to associated runtime overhead, it also results in a continuous softirq loop when the interface is brought down under heavy traffic(tested wit Traffic Generator). Once the interface is disabled, the poll function always returns zero(with the check for netif_running) and napi_complete() would never get called resulting in softirq loop.
