[S390] cio: Fix incomplete commit for uevent suppression.

Browse Source 
Commit fa1a8c23eb intended to
introduce uevent suppression for subchannels, but half of it was
lost somewhere. Now, we end up with two uevents for every registered
subchannel :( So we should better add the missing part from
http://marc.info/?l=linux-kernel&m=117515953113974&w=2.
