net: phy: mxl-gpy: fix bogus error on USXGMII and integrated PHY

Browse source

[ Upstream commit ec3803b591 ]

As the interface mode doesn't need to be updated on PHYs connected with
USXGMII and integrated PHYs, gpy_update_interface() should just return 0
in these cases rather than -EINVAL which has wrongly been introduced by
commit 7a495dde27 ("net: phy: mxl-gpy: Change gpy_update_interface()
function return type"), as this breaks support for those PHYs.

Fixes: 7a495dde27 ("net: phy: mxl-gpy: Change gpy_update_interface() function return type")
