It fixed the EP number wrong issue at trace when the TRBERR interrupt occurs for EP0IN. When the EP0IN IOC has finished, software prepares the setup packet request, the expected direction is OUT, but at that time, the TRBERR for EP0IN may occur since it is DMULT mode, the DMA does not stop until TRBERR has met.
