scsi: megaraid_sas: latest controller OCR capability from FW before sending shutdown DCMD

Orabug: 26096381

Fetch the latest controller OCR capability from FW before sending
MR_DCMD_CTRL_SHUTDOWN When application sends a shutdown DCMD
(MR_DCMD_CTRL_SHUTDOWN), driver will fetch latest controller information
from firmware.  This is to ensure that driver always has latest OCR
capability of controller before sending the DCMD.
