[PATCH net 04/10] net: ethernet: adi: Move setting of netops to fix crash

[David Yang <mmyangfl@gmail.com>]

adin1140_probe() calls adin1140_phy_init(), which connects the PHY,
before netdev->netdev_ops is assigned. 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")
