[S390] cio: Fix incomplete commit for uevent suppression.
Commit fa1a8c23eb7d3ded8a3c6d0e653339a2bc7fca9e 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.
