Subject: [PATCH v2 net-next] net: mscc: ocelot: omit error check from of_get_phy_mode

The commit 0c65b2b90d13c ("net: of_get_phy_mode: Change API to solve
int/unit warnings") updated the function of_get_phy_mode declaration.
Now it returns an error code and in case the node doesn't contain the
property 'phy-mode' or 'phy-connection-type' it returns -EINVAL and would
set the phy_interface_t to PHY_INTERFACE_MODE_NA.

Ocelot VSC7514 has 4 internal phys which have the phy interface
PHY_INTERFACE_MODE_NA. So because of_get_phy_mode would assign
PHY_INTERFACE_MODE_NA to phy_mode when there is an error, there is no need
to add the error check.

Updates for v2:
- drop error check because of_get_phy_mode already assigns phy_interface
to PHY_INTERFACE_MODE in case of error.
