The comments for lkdtm_do_action() explicitly call out that it shouldn't be inlined because we want it to show up in stack crawls. However, at least with some compilers / options it's still vanishing due to tail call optimization. Let's add a return value to the function to make it harder for the compiler to do tail call optimization here. Now that we have a return value, we can actually use it in the callers, which is a minor improvement in the code.
