ieee1394: fix oops on "modprobe -r ohci1394" after network class_device conversion

Browse Source 
The networking subsystem has been converted from class_device to device
but ieee1394 hasn't.  This results in a 100% reproducible NULL pointer
dereference if the ohci1394 driver module is unloaded while the eth1394
module is still loaded.

This is a regression in 2.6.21-rc1.
