libertas: set mac control synchronously during init
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.
