[SCSI] ipr: set the data list length in the request control block
In bring up testing for the new 64 bit adapters, the first read command failed after loading the driver. The cause was that the command requires more than one scatter gather element and the corresponding code to set the data list length in the request control block was missing. This patch adds the correct assignment.
