[PATCHv2 net] net: ll_temac: Return actual error from of_get_mac_address()

[Rosen Penev <rosenp@gmail.com>]

When of_get_mac_address() fails, return the actual error code (rc)
instead of the hardcoded -ENODEV. This preserves the original error
information, which may be more specific (e.g., -EINVAL, -EPROBE_DEFER)
and helps callers handle the failure appropriately.

Use dev_err_probe() to avoid printing an extra error message in case of
-EPROBE_DEFER.

Fixes: 8425c41d1ef7 ("net: ll_temac: Extend support to non-device-tree platforms")
