    sched: Fix the broken sched_rr_get_interval()

Without this patch, syscall sched_rr_get_interval() can return wrong
value, and the bug was introduced in 2.6.24, so this looks like a
candidate for stable kernel.

The concern for backporting is that this might break some userspace
programs? As the changelog says:

    [ Since this is an ABI and an old bug, we'll test this via a
      slow upstream route, to hopefully discover any app breakage. ]
