Fix bug introduced in last change. GATT define was after BLE_INCLUDED define.

The bug caused GATT_INCLUDED to be FALSE if not already defined.

Looks like the bluedroid codebase really can't support no GATT or SMP
if BLE_INCLUDED is true.  Lots of compiler failures (not just warnings but
real failures) if GATT or SMP are not set to TRUE when BLE_INCLUDED is true.

Not cleaning that up at this time but just fixing basic build breakage.
