via-cuda: Initialize data_index early and increment consistently
Initialize data_index where appropriate to improve readability and
assist debugging. This change doesn't affect driver behaviour.
I prefer to see
current_req->data[data_index++]
in place of
current_req->data[0]
or
current_req->data[1]
inasmuchas it becomes obvious what the data_index variable does.
Moreover, the actual value of data_index when examined at any given moment
tells me something about prior events, which did prove helpful.
