kernel: Move SMP initialization to start of main thread
The smp_init() call was too early. Device and subsystem
initialization doesn't happen until after the main thread starts
running. Starting extra CPUs and allowing them to schedule threads
before their drivers are alive is a bad idea, even if it works in a
unit test.
