Subject: [PATCH AUTOSEL 6.12 264/486] scsi: mpi3mr: Update timestamp only for supervisor IOCs

From: Ranjan Kumar <ranjan.kumar@...adcom.com>

[ Upstream commit 83a9d30d29f275571f6e8f879f04b2379be7eb6c ]

The driver issues the time stamp update command periodically. Even if the
command fails with supervisor only IOC Status.

Instead check the Non-Supervisor capability bit reported by IOC as part of
IOC Facts.
