Subject: [PATCH net-next] net: phy: aquantia: fix return value check in
 aqr107_config_mdi()

of_property_read_u32() returns -EINVAL in case the property cannot be
found rather than -ENOENT. Fix the check to not abort probing in case
of the property being missing.

Fixes: a2e1ba275eae ("net: phy: aquantia: allow forcing order of MDI pairs")
