drm/virtio: fix bounds check in virtio_gpu_cmd_get_capset()
This doesn't affect runtime because in the current code "idx" is always
valid.
First, we read from "vgdev->capsets[idx].max_size" before checking
whether "idx" is within bounds. And secondly the bounds check is off by
one so we could end up reading one element beyond the end of the
vgdev->capsets[] array.
