block: fix request sorting at unplug
Comparison function for list_sort() must be anticommutative,
otherwise it is not sorting in ordinary meaning.
But fortunately list_sort() always check ((*cmp)(priv, a, b) <= 0)
it not distinguish negative and zero, so comparison function can
implement only less-or-equal instead of full three-way comparison.
