Avoid setting AS key when OTP preauth fails

In otp_client_process(), call cb->set_as_key() later in the function
after the OTP request has been created.  The previous position of this
call caused the AS key to be replaced even when later code in the
function failed, preventing other preauth mechanisms from retrieving
the correct AS key.
