[SCSI] ipr: Handle check condition status from disk array device
On newer levels of microcode for ipr RAID adapters supporting
multi-initiator configurations, the disk array, or VSET, resources
are capable of generating a check condition. This patch prevents
ipr from generating sense data in this scenario and retrieving it
from the logical device instead.
