When using a virt_boundary_mask, as done for NVMe devices attached to mpt3sas controllers, we require an unlimited max_segment_size as the virt boundary merging code assumes that. But we also need to propagate that to the DMA mapping layer to make dma-debug happy. The SCSI layer takes care of that when using the per-host virt_boundary setting, but given that mpt3sas only wants to set the virt_boundary for actual NVMe devices, we can't rely on that. The DMA layer maximum segment is global to the HBA however, so we have to set it explicitly. This patch assumes that mpt3sas does not have a segment size limitation, which seems true based on the SGL format, but will need to be verified.
