Instead of reading the requested rx queues after binding the buffer,

This is a preparation for fetching the DMA device for each queue.

This patch has no functional changes.

Nice!

FWIW I think you can use num_real_rx_queues since we're holding
the instance lock which prevents it from changing?

But it's just bits so doesn't matter all that much.
