__bcmgenet_tx_reclaim() is not using the struct device reference when
doing its unmap operation, which made the DMA-API debugging warn about
it. Fix this by always using &priv->pdev->dev throughout the driver,
using an identical device reference for all map/unmap calls.
Fixes: 1c1008c793fa ("net: bcmgenet: add main driver file")
