_ops after it's
unloaded. So if we modprobe then rmmod microcode, the stale
microcode syscore_ops info will stay on syscore_ops_list.

Later when we're trying to reboot/halt/shutdown the machine, kernel
will panic on syscore_shutdown().

With the patch applied, I can reboot/halt/shutdown my machine successfully.
