caif: unlock on error path in cfserl_receive()
There was an spin_unlock missing on the error path. The spin_lock was tucked in with the declarations so it was hard to spot. I added a new line. Signed-off-by: Dan Carpenter <error27@gmail.com> Acked-by: Sjur Brændeland <sjurbren@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
