scsi: communicate max segment size to the DMA mapping code
When a host driver sets a maximum segment size we should not only propagate
that setting to the block layer, which can merge segments, but also to the
DMA mapping layer which can merge segments as well.
Fixes: 50c2e9107f ("scsi: introduce a max_segment_size host_template parameters")
