[PATCH v2 1/3] dmaengine: virt-dma: don't always free descriptor upon completion

This patch attempts to enhance the case of a transfer submitted multiple times, and where the cost of creating the descriptors chain is not negligible. This happens with big video buffers (several megabytes, ie. several thousands of linked descriptors in one scatter-gather list). In these cases,
