Subject: [PATCH 7/8] neterion/s2io: fix s2io_set_mac_addr() to prevent double checks

Fix s2io_set_mac_addr() to prevent double validation checks from
dev_set_mac_address().

Don't use s2io_set_mac_addr() in s2io_io_resume() since it makes
no sense to copy netdev->dev_addr to itself. Use do_s2io_prog_unicast()
instead since this is what's needed and checked here.
