[SCSI] zfcp: create private slab caches to guarantee proper data alignment
Create private slab caches in order to guarantee proper alignment of
data structures that get passed to hardware.
Sidenote: with this patch slab cache debugging will finally work on s390
(at least no known problems left).
Furthermore this patch does some minor cleanups:
- store ptr for transport template in struct zfcp_data
