scsi: wd719x: use per-command private data
Add the SCB onto the scsi command allocation and use dma streaming mappings
for it only when in use. This avoid possibly calling dma_alloc_coherent
under a lock or even in irq context, while also making the code simpler.
Thanks to Ondrej Zary for testing and various bug fixes.
