Return AEE_ECONNREFUSED when Fastrpc device is not available

Currently, during device open, if Fastrpc device is not available AEE_ERPC error code is returned. AEE_ERPC is a generic error code and clients are not expecting AEE_ERPC in this scenario. To address this, change the error code to AEE_ECONNREFUSED. Signed-off-by: ANANDU KRISHNAN E <[email protected]>
