Fatal error in OCS(overall command status) field indicates
error conditions which is not covered by UFSHCI.
It means that host cannot define the result of command status
and therefore host may need to check transfer response UPIU's
response and status field.
It was actually found that 'CHECK CONDITION' is stored in status
field of UPIU where OCS is 'FATAL ERROR'.
