kernel: ext4: don't set SB_RDONLY after filesystem errors

A flaw was found in the Linux kernel's handling of filesystem errors. When a filesystem encounters an error and is configured to remount as read-only, the kernel's attempt to apply this setting can conflict with other filesystem operations, specifically during filesystem freezing. This conflict c...
