virtio: virtqueue_get_avail_bytes: fix desc_pa when loop over the indirect descriptor table
virtqueue_get_avail_bytes: when found a indirect desc, we need loop over it.
/* loop over the indirect descriptor table */
indirect = 1;
max = vring_desc_len(desc_pa, i) / sizeof(VRingDesc);
num_bufs = i = 0;
desc_pa = vring_desc_addr(desc_pa, i);
But, It init i to 0, then use i to update desc_pa. so we will always get:
desc_pa = vring_desc_addr(desc_pa, 0);
the last two line should swap.
