[PATCH resend] rsi: Fix a potential memory leak in rsi_send_auto_rate_request()

[Christian Engelmayer]

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.
