net: tile: Use helpers from linux/etherdevice.h to check/set MAC
Use is_zero_ether_addr() to check for the MAC address being all zeros instead of
open coding the check.
Also use ether_addr_copy() instead of a manual memcpy() to set the
netdev->dev_addr.
Furthermore, get rid of a redundant assignment of netdev->addr_len. This is
already set by ether_setup() which is called in tile_net_setup().
