[PATCH] module_subsys: initialize earlier

Initialize module_subsys earlier (or at least earlier than devices) since
it could be used very early in the boot process if kmod loads a module
before the device initcalls.  Otherwise, kmod will crash in
kernel/module.c:mod_sysfs_setup() since the kset in module_subsys is not
initialized yet.

I only noticed this problem because occasionally, kmod loads the modules
for my SCSI and Ethernet adapters very early, during the boot process
itself.  I don't quite understand why it loads them sometimes and doesn't
load them other times.  Or who is telling kmod to do so.  Can someone
explain?
