[ Upstream commit 8876529465c368beafd51a70f79d7a738f2aadf4 ]

Fix Pause Frame Advertising when getting the advertisement via ethtool.
Remove setting the "advertising" bit in link_ksettings during default
case when Tx and Rx are in off state with Auto Negotiate off.

Below is the original output of advertisement link during Tx and Rx off:
Advertised pause frame use: Symmetric Receive-only

Expected output:
Advertised pause frame use: No
