dahdi: Update dev_set_name / dev_name for RHEL 5.6+.

Browse Source 
This is needed because dev_name() is mapped to kobject_name() in a backport,
but the kobject name isn't set until after device_add().  The result would be
parentless devices would fail since dahdi would not think a name was set for
these devices.

For these systems, we'll set both the bus_id string and the underlying
kobject_name.
