net: phylink: move phy_device_free() to correctly release phy device
After calling fwnode_phy_find_device(), the phy device refcount is
incremented. Then, when the phy device is attached to a netdev with
phy_attach_direct(), the refcount is also incremented but only
decremented in the caller if phy_attach_direct() fails. Move
phy_device_free() before the "if" to always release it correctly.
Indeed, either phy_attach_direct() failed and we don't want to keep a
reference to the phydev or it succeeded and a reference has been taken
internally.
