rsi: fix memory leak on failed URB submission
commit 47768297481184932844ab01a86752ba31a38861 upstream.
Make sure to free the skb on failed receive-URB submission (e.g. on
disconnect or currently also due to a missing endpoint).
Fixes: a1854fae1414 ("rsi: improve RX packet handling in USB interface")
