[PATCH 23/23] agp/generic: Set the dma_addr[i] to DMA_ERROR_CODE

[Konrad Rzeszutek Wilk]

Set the dma_addr[i] to DMA_ERROR_CODE so it will be the
responsibility of the caller to set the dma_addr[i] to the right
value. Currently the callers that would utililize this are then ones
that set the type to AGP_USER_TYPES are the TTM and DRM APIs.
