net: designware: fix bus address dereference

Device bus address might not be valid for direct access when the bus
address and CPU address are not the same. Use dev_bus_to_phys() to
translate bus address back to CPU address.

Fixes: 3d98b8c504e15 ("net: designware: Invalidate RX buffer cache before freeing the DMA descriptor")
