Subject: [PATCH AUTOSEL 6.6 023/104] net: usb: ax88179_178a: avoid two consecutive device resets

From: Jose Ignacio Tornos Martinez <jtornosm@...hat.com>

[ Upstream commit d2689b6a86b9d23574bd4b654bf770b6034e2c7e ]

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.

Remove the non-necessary reset during the device binding and let the reset
operation from open to keep the normal behavior (tested with generic ASIX
Electronics Corp. AX88179 Gigabit Ethernet device).
