hulk inclusion category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9Q98W CVE: CVE-2024-35808
--------------------------------
MD_RECOVERY_FROZEN should always remain set after array is frozen. But in raid_message(), this flag is cleared soon after frozen. Fix it. This flag will be cleared in md_idle_sync_thread(), there is no need to clear it again for idle.
