[PATCH net 10/10] microchip: lan865x: move setting of netops to fix crash

lan865x_probe() assigns netdev_ops only after oa_tc6_init(), which
connects the internal MAC-PHY through phy_connect_direct().
phy_attach_direct() -> phy_link_topo_add_phy() reads dev->netdev_ops
through netdev_need_ops_lock() since the commit in question, so probing
crashes with a NULL pointer dereference when CONFIG_NET_SHAPER is
enabled.

Assign netdev_ops before the PHY attach, as was done for emac in commit
7c9f391ec89c ("net: emac: move setting of netops to fix crash").

Fixes: ded86da4bbb7 ("net: ethtool: relax ethnl_req_get_phydev() locking assertion")
