iotlb_translate() can return -ENOBUFS if the bio_vec is not big enough to contain all the ranges for translation. This can happen for example if the VMM maps a large bounce buffer, without using hugepages, that requires more than 16 ranges to translate the addresses. To handle this case, let's extend iotlb_translate() to also return the number of bytes successfully translated. In copy_from_iotlb()/copy_to_iotlb() loops by calling iotlb_translate() several times until we complete the translation.
