[PATCH net-next v4 15/15] net: stmmac: use queue rather than ->queue_index

[Russell King (Oracle)]

We use a lot of ->queue_index where we already have the queue / channel
index (which are actually the same index), which has been used to get
the queue struct. Since queue and queue_index are identical in
priv->(tx|rx)_queue[queue]->queue_index there is no point using the
queue_index where we already have queue.

Use queue rather than queue_index.
