net: usb: ax88179_178a: avoid the interface always configured as random address
After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two
consecutive device resets"), reset is not executed from bind operation and
mac address is not read from the device registers or the devicetree at that
moment. Since the check to configure if the assigned mac address is random
or not for the interface, happens after the bind operation from
usbnet_probe, the interface keeps configured as random address, although the
address is correctly read and set during open operation (the only reset
now).
In order to keep only one reset for the device and to avoid the interface
always configured as random address, after reset, configure correctly the
suitable field from the driver, if the mac address is read successfully from
the device registers or the devicetree. Take into account if a locally
administered address (random) was previously stored.
