kern/thread: support thread_sleep without interlock
The thread_sleep function takes a spin lock as a parameter. This lock is
used as an interlock allowing either the thread waking up or the thread
being awaken to run. But when threads don't need a lock to provide that
guarantee, the interlock is only overhead. This change makes thread_sleep
assume disabling preemption is used as a synchronization mechanism when
the interlock is NULL.
