RDMA: Use default_groups in kobj_type

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
IB code to use default_groups field which has been the preferred way since
commit aa30f47cf666 ("kobject: Add support for default attribute groups to
kobj_type") so that we can soon get rid of the obsolete default_attrs
field.
