rsi: Fix a potential memory leak in rsi_send_auto_rate_request()
Fix a potential memory leak in the error path of function rsi_send_auto_rate_request(). In case memory allocation for array 'selected_rates' fails, the error path exits and leaves the previously allocated skb in place. Detected by Coverity: CID 1195575.
