swiotlb: silent unwanted warning "buffer is full"
If DMA_ATTR_NO_WARN is passed to swiotlb_alloc_buffer(), it should be
passed further down to swiotlb_tbl_map_single(). Otherwise we escape
half of the warnings but still log the other half.
This is one of the multiple causes of spurious warnings reported at:
