Pablo Bitton 64c8165b44 davinci_emac: fix kernel oops when changing MAC address while interface is down ...

Check that network interface is running before changing its MAC address.
Otherwise, rxch is accessed when it's NULL - causing a kernel oops.
Moreover, check that the new MAC address is valid.
