Hans Verkuil 18e16f9c95 V4L/DVB (6342): ivtv: fix circular locking (bug 9037)
If you try to access the video device from within an udev rule,
then you get into a circular locking situation.

Changed the driver to postpone the registration of the devices until
everything else has been fully initialized, so that the newly created
device can be used immediately.
