Additional info for failed SAT-Send USSD case

Additional info for failed SAT-Send USSD case

Hi,

 Following patch handles the SAT initiated Send USSD failure case. 
As per the 3GPP 31.111 specification section 6.4.12, when a SAT initiated 
Send USSD fails, error code from the network should be sent as 
additional information(part of Result data). If no additional information
can be sent, then 0( No specific cause can be given) should be sent.

 Due to the current limitations, this patch sends "No Specific cause can be 
givent" to the SAT.

Regards,
jeevaka

Hi Jeevaka,

> +	unsigned char addnl;

Lets try to be consistent with other parts of stk.c.
Use unsigned char no_cause[] = { 0x00 };

Then rsp.result.additional_len = sizeof(no_cause);
rsp.result.additional = no_cause

Otherwise looks good.
