Dragos Tatulea b8aab4bb95 net: devmem: allow binding on rx queues with same DMA devices ...

Multi-PF netdevs have queues belonging to different PFs which also means
different DMA devices. This means that the binding on the DMA buffer can
be done to the incorrect device.

This change allows devmem binding to multiple queues only when the
queues have the same DMA device. Otherwise an error is returned.
