Whenever IO for raid volume fails with IOCStatus
"MPI2_IOCSTATUS_SCSI_IOC_TERMINATED"and SCSIStatus equal to
"(MPI2_SCSI_STATE_TERMINATED | MPI2_SCSI_STATE_NO_SCSI_STATUS)"
then return the IO to SML with "DID_RESET"
(i.e. retry the IO infinite times) host bytes.
Earlier driver is returning the IO with "DID_SOFT_ERROR"
that reties the IO quickly for five times but still
firmware needed some more time and hence IOs were failing.
