usb-storage: fix sdev->host->dma_dev
Use scsi_add_host_with_dma() instead of scsi_add_host().
When the scsi request queue is initialized/allocated, hw_max_sectors is clamped
to the dma max mapping size. Therefore, the correct device that should be used
for the clamping needs to be set.
The same clamping is still needed in usb-storage as hw_max_sectors could be
changed there. The original clamping would be invalidated in such cases.
