[LTP] [PATCH] tst_timer: fix qsort comparison function

[Piotr Gawel]

>From qsort() manual:
    The  comparison  function must return an integer
    less than, equal to, or greater than zero if the
    first argument is considered to be respectively
    less than, equal to, or greater than the second.
    If two members compare as equal, their order in
    the sorted array is undefined.
We need it in descending order so the logic is
reverted.
