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.

In some situations \fBchzdev\fR will attempt to load kernel modules to
complete a configuration action. This behavior may be undesirable in some
scenarios. The \fB\-\-no-module-load\fR option suppresses kernel module loading
