Anirudh Rayabharam 7480cc0240 vhost: handle error while adding split ranges to iotlb ... commit 03a91c9af2 upstream. vhost_iotlb_add_range_ctx() handles the range [0, ULONG_MAX] by splitting it into two ranges and adding them separately. The return value of adding the first range to the iotlb is currently ignored. Check the return value and bail out in case of an error.
