[PATCH] net: stmmac: don't use netdev_[dbg, info, ..] before net_device is registered

[Heiner Kallweit]

Don't use netdev_info and friends before the net_device is registered.
This avoids ugly messages like
"meson8b-dwmac c9410000.ethernet (unnamed net_device) (uninitialized):
Enable RX Mitigation via HW Watchdog Timer"

Indeed, this is a side-effect of the MDIO vs. register_netdev race fix
that went in the other week.

Applied, thanks.
