Peter Ujfalusi fdfd8f9ef2 dmaengine: virt-dma: Fix access after free in vchan_complete() 
commit 24461d9792 upstream.

vchan_vdesc_fini() is freeing up 'vd' so the access to vd->tx_result is
via already freed up memory.

Move the vchan_vdesc_fini() after invoking the callback to avoid this.

Fixes: 09d5b702b0 ("dmaengine: virt-dma: store result on dma descriptor")
