kset: convert kernel_subsys to use kset_create
Dynamically create the kset instead of declaring it statically. We also rename kernel_subsys to kernel_kset to catch all users of this symbol with a build error instead of an easy-to-ignore build warning. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
