s390/cio: avoid duplicated 'ADD' uevents
[ Upstream commit 05ce3e53f375295c2940390b2b429e506e07655c ]
The common I/O layer delays the ADD uevent for subchannels and
delegates generating this uevent to the individual subchannel
drivers. The io_subchannel driver will do so when the associated
ccw_device has been registered -- but unconditionally, so more
ADD uevents will be generated if a subchannel has been unbound
from the io_subchannel driver and later rebound.
To fix this, only generate the ADD event if uevents were still
suppressed for the device.
Fixes: fa1a8c23eb7d ("s390: cio: Delay uevents for subchannels")
