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