libertas: convert CMD_802_11_MAC_ADDRESS to a direct command
* directly call lbs_cmd_with_response() * only overwrite priv->current_addr once the firmware call succeeded Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Acked-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
