ieee1394: fix host device registering when nodemgr disabled

Browse Source 
Since my commit 8252bbb1363b7fe963a3eb6f8a36da619a6f5a65 in 2.6.20-rc1,
host devices have a dummy driver attached.  Alas the driver was not
registered before use if ieee1394 was loaded with disable_nodemgr=1.

This resulted in non-functional FireWire drivers or kernel lockup.
