drbd: cleanup: change "<= 0" to "== 0"
dt is unsigned so it's never less than zero. We are calculating the elapsed time, and that's never less than zero (unless there is a bug or we invent time travel). The comparison here is just to guard against divide by zero bugs. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com>
