dm: delay registering the gendisk
device mapper is currently the only outlier that tries to call
register_disk after add_disk, leading to fairly inconsistent state
of these block layer data structures. Instead change device-mapper
to just register the gendisk later now that the holder mechanism
can cope with that.
Note that this introduces a user visible change: the dm kobject is
now only visible after the initial table has been loaded.
