zdev: Introduce --no-module-load option for chzdev

Browse Source 
When called with a device parameter, chzdev tries to load the kernel
module of the corresponding device type. This might not be desired in
certain situations like early initial RAM-disk processing.

To support this use cases, add a new command-line option
--no-module-load to prevent the loading of any kernel module by chzdev.
