Bluetooth: Revert SMP self-test patches 



This reverts commits c6992e9e and
4cd3362d.

The reason for the revert is that we cannot have more than one module
initialization function and the SMP one breaks the build with modular
kernels. As the proper fix for this is right now looking non-trivial
it's better to simply revert the problematic patches in order to keep
the upstream tree compilable.
