dmaengine: at_xdmac: fix to pass correct device identity to free_irq()

commit 6a8b0c6b upstream.

free_irq() expects the same device identity that was passed to
corresponding request_irq(), otherwise the IRQ is not freed.

Fixes: e1f7c9ee ("dmaengine: at_xdmac: creation of the atmel eXtended DMA Controller driver")
