zdev: Trigger generic_ccw devices on any kernel module loads.

Browse Source 
Generic CCW device can use any driver, and the value of the driver is
not known ahead of time. To avoid the race between loading and binding
a kernel module, and devices added - retrigger generic-ccw devices on
any kernel module load.
