Subject: [PATCH 2/2] net: usb: ax88179_178a: avoid two consecutive device resets

The device is always reset two consecutive times (ax88179_reset is called
twice), one from usbnet_probe during the device binding and the other from
usbnet_open.

Let only the reset during the device binding to prepare the device as soon
as possible and not repeat the reset operation (tested with generic ASIX
Electronics Corp. AX88179 Gigabit Ethernet device).
