 Log Message:
 tests/lib/libc/sys/t_futex_ops: Fix FUTEX_CMP_REQUEUE return values.
 
 The return value is the number of waiters woken _or requeued_, not
 just the number of waiters woken:
 
    FUTEX_CMP_REQUEUE
           Returns the total number of waiters that were woken up or
           requeued to the futex for the futex word at uaddr2.  If
           this value is greater than val, then the difference is the
           number of waiters requeued to the futex for the futex word
           at uaddr2.
