[PATCH net 02/10] net: hisilicon: hip04_eth: Move setting of netops to fix crash

[David Yang <mmyangfl@gmail.com>]

hip04_mac_probe() calls of_phy_connect() before ndev->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")
