drivers: net: ethernet: davinci_emac: use netif_wake_queue() while restarting tx...

commit 7e51cde276ca820d526c6c21cf8147df595a36bf upstream.

To restart tx queue use netif_wake_queue() intead of netif_start_queue()
so that net schedule will restart transmission immediately which will
increase network performance while doing huge data transfers.
