btrfs: sysfs: Replace default_attrs in ktypes with groups 

The kobj_type default_attrs field is being replaced by the
default_groups field. Replace the default_attrs fields in
btrfs_raid_ktype and space_info_ktype with default_groups.

Change "raid_attributes" to "raid_attrs", and use the ATTRIBUTE_GROUPS
macro to create raid_groups and space_info_groups.
