[PATCH 1/2] net/usb/ax88179_178a: Use common code in ax88179_chk_eee()

[SF Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 10 Mar 2018 18:22:43 +0100

Adjust a jump target so that a bit of common code can be better reused
at the end of this function.

This issue was detected by using the Coccinelle software.
