scsi: ufs: core: Update CQ Entry to UFS 4.1 format
Update the completion queue (CQ) entry format according to the UFS 4.1
specification. UFS 4.1 introduces new members in reserved record
DW5. Also refine DW4 with detailed members defined in UFS 4.0. Modify
the code to incorporate these changes by updating the overall_status in
the CQ entry structure.
