dm9000: Return an ERR_PTR() in all error conditions of dm9000_parse_dt()
In one error condition dm9000_parse_dt() returns NULL, however the
return value is checked using IS_ERR() in dm9000_probe(), leading to the
error not being properly propagated if CONFIG_OF is not enabled or the
device tree data is not available. Fix this by also returning an
ERR_PTR() in this case.
