There are currently 2 ways to create a set of sysfs files for a
kobj_type, through the default_attrs field, and the default_groups
field.  Move the bcache sysfs code to use default_groups field which has
been the preferred way since aa30f47cf666 ("kobject: Add support for
default attribute groups to kobj_type") so that we can soon get rid of
the obsolete default_attrs field.

It looks good to me.

Acked-by: Coly Li <colyli@suse.de>

I assume you may take this patch directly in your maintenance path, but 
if you want me to take this, just let me know. Thanks.

I can take it myself, or you can, which ever is easiest for you, just
let me know which you prefer.  Thanks for the review!
