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.

This patch depends on a patch in the driver-core tree: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git/commit/?h=driver-core-next&id=aa30f47cf666111f6bbfd15f290a27e8a7b9d854

GregKH can take this patch through the driver-core tree, or this patch
can wait a release cycle and go through the subsystem's tree, whichever
the subsystem maintainer is more comfortable with.

Please take it through the driver-core tree, thanks.
