Increment qtd->isoc_frame_index_last before testing it, else below
check will never be true and IOC (Interrupt On Complete) bit for
last frame will never be set in descriptor status.
/* Set IOC for each descriptor corresponding to last frame of URB */
if (qtd->isoc_frame_index_last == qtd->urb->packet_count)
dma_desc->status |= HOST_DMA_IOC;
