			CMD_MAC_CONTROL is currently sent async to the firmware, and is sent from the lbs_setup_firmware() path during device init. This means that device init can complete with commands pending, and the if_sdio driver will sometimes power down the device (after init) with this command still pending. This was causing an occasional spurious command timeout after init, leading to a device reset. Fix this by making CMD_MAC_CONTROL synchronous when called from the lbs_setup_firmware() path.
