[SCSI] Fix ibmvscsi client for multiplatform iSeries+pSeries kernel
If you build a multiplatform kernel for iSeries and pSeries, with
ibmvscsic support, the resulting client doesn't work on iSeries.
This fixes that, using the appropriate low-level operations
for the machine detected at runtime.
[jejb: fixed up rejections around the srp transport patch]
