This patch (as1159b) changes the timeout routines in the block core to
use round_jiffies_up(). There's no point in rounding the timer
deadline down, since if it expires too early we will have to restart
it.
The patch also removes some unnecessary tests when a request is
removed from the queue's timer list.
