    [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]
