virtio: fix up max size checks
Coverity reports that ARRAY_SIZE(elem->out_sg) (and all the others too)
is wrong because elem->out_sg is a pointer.
However, the check is not in the right place and the max_size argument
of virtqueue_map_iovec can be removed. The check on in_num/out_num
should be moved to qemu_get_virtqueue_element instead, before the call
to virtqueue_alloc_element.
