platform/x86/amd/hsmp: Clear mdev.this_device on deregister
misc_deregister() destroys the device but leaves miscdevice.this_device
pointing at the freed struct device. Clear it so any later check of
this_device, and a subsequent re-register, does not observe a stale
pointer. An upcoming change uses this_device to track whether /dev/hsmp is
registered across the shared ACPI sockets and relies on it being NULL after
deregister.
