[MachinePipeliner] Fix risky iterator usage R++, --R
When we calculate MII, we use two loops, one with iterator R++ to
check whether we can reserve the resource, then --R to move back
the iterator to do reservation.
This is risky, as R++, --R may not point to the same element at all.
The can cause wrong MII.
