When plugging some webcams on ARM, the system crashes. This is because we alloc buffer for an urb through usb_buffer_alloc, the alloced buffer is already in DMA coherent region, so we should set the flag of this urb to URB_NO_TRANSFER_DMA_MAP, otherwise when we submit this urb, the hcd core will handle this address as an non-DMA address and call dma_map_single/sg to map it. On arm architecture, dma_map_single a DMA coherent address will be catched by a BUG_ON().
