virtio-gpu: move iov free to virtio_gpu_cleanup_mapping_iov
For symmetry reasons: virtio_gpu_create_mapping_iov() allocates it so virtio_gpu_cleanup_mapping_iov() should free it, otherwise it's easy to miss a free() needed and leak memory. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Reviewed-by: Max Reitz <mreitz@redhat.com>
