Close a race in sleepq_broadcast() where the sleepq could be reused after
it had been assigned to the last sleeping thread. That thread might have
started running on another CPU and have reused that sleep queue. Fix it
by just walking the thread queue using TAILQ_FOREACH_SAFE() rather than
a while loop.
