shadowlock: disable until proper unit tests are run

This code as-is is not doing anything other then declaring a function.
The solution is to utilize {} to tell the compiler it's an object
instantiation. Given that this code has been a noop up until this point,
it's best to just comment it out until someone can come in enable and
test it properly.

The latest yocto update which brings in a newer compiler is erroring out
on this so we need something quick to be able to make progress there.

openbmc/phosphor-host-ipmid#170 is tracking this issue.
