net: dsa: Set valid phy interface type
If the phy interface mode is not found in devicetree, or if devicetree
is not configured, of_get_phy_mode returns -ENODEV. The current code
sets the phy interface mode to the return value from of_get_phy_mode
without checking if it is valid.
This invalid phy interface mode is passed as parameter to of_phy_connect
or to phy_connect_direct. This sets the phy interface mode to the invalid
value, which in turn causes problems for any code using phydev->interface.

Fixes: 0d8bcdd383b8 ("net: dsa: allow for more complex PHY setups")
