rpmsg: fix dma_free_coherent dev parameter
dma_alloc/free_coherent APIs requires the platform specific remoteproc device as the device parameter. We are passing vdev->dev.parent to the dma_free_coherent function which is the generic rproc device and it is wrong, it has to be vdev->dev.parent->parent instead, same as when we call dma_alloc_coherent function.
