For use with multi-path, it is very useful to have the path in the
scsi_cmnd, and generally to not have the lldd's know about the scsi_device
at all, such that we can pick a path, and send a scsi_cmnd to a lldd.

Putting path information only in scsi_device makes it hard to do
multi-path below (or even in) the block layer, and makes it hard to
multi-path non block devices (like tape).

I would prefer we keep the current scsi_cmnd with its
host/channel/target[id]/lun.
