[PATCH net v2] ibmvnic: save changed mac address to adapter->mac_addr

[Lijun Pan]

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")
