alpha/cpu: Make sure arch_cpu_idle_dead() doesn't return
arch_cpu_idle_dead() doesn't return. Make that more explicit with a
BUG().
BUG() is preferable to unreachable() because BUG() is a more explicit
failure mode and avoids undefined behavior like falling off the edge of
the function into whatever code happens to be next.
