Btrfs: sysfs: let default_attrs be separate from the kset
As of now btrfs_attrs are provided using the default_attrs through the kset. Separate them and create the default_attrs using the sysfs_create_files instead. By doing this we will have the flexibility that device discovery thread could create fsid kobject. Signed-off-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.cz>
