Bluetooth: Revert SMP self-test patches

This reverts commits ea53ec2759da47fc5efaa5ff42b2781ffd78c43c and
570751ad52b262e6d9d9a6b212cb4d41abed8f81.

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.
