[ Upstream commit d9b0e599b2b892422f1cbc5d2658049b895b2b58 ]
After mac address change request completes successfully, the new mac
address need to be saved to adapter->mac_addr as well as
netdev->dev_addr. Otherwise, adapter->mac_addr still holds old
data.
Fixes: 62740e97881c ("net/ibmvnic: Update MAC address settings after adapter
reset")
