net: arc_emac: Make use of the helper function dev_err_probe()
When possible use dev_err_probe help to properly deal with the PROBE_DEFER error, the benefit is that DEFER issue will be logged in the devices_deferred debugfs file. And using dev_err_probe() can reduce code size, and simplify the code. Signed-off-by: Cai Huoqing <caihuoqing@baidu.com> Signed-off-by: David S. Miller <davem@davemloft.net>
