[PATCH net-next] ibmvnic: Assign XPS map to correct queue index

[Nick Child <nnac123@linux.ibm.com>]

When setting the XPS map value for TX queues, use the index of the
transmit queue.
Previously, the function was passing the index of the loop that iterates
over all queues (RX and TX). This was causing invalid XPS map values.

Fixes: 6831582937bd ("ibmvnic: Toggle between queue types in affinity mapping")

I am a little surprised that __netif_set_xps_queue() did not complain that some
index values were greater than the number of tx queues. Though maybe the function
assumes that the developers are wise enough :)

Should __netif_set_xps_queue() have a check that index < dev->num_tx_queues?
