Make sure SStatus of link reaches stable state, determined by
holding the same value where DET is not 1 for duration polled
every interval, before timeout. Timeout constraints the
beginning of the stable state. Because DET gets stuck at 1 on
some controllers after hot unplugging, this functions waits
until timeout then returns 0 if DET is stable at 1.
timeout is further limited by deadline. The sooner of the
two is used.
