The code do reduce or increase the weight by comparing
`benchmarked_weight` and `consumed_weight`.

But `benchmarked_weight` is the pre dispatch weight. not the post
dispatch weight that is actually written into the block weight by
`CheckWeight`.

So in case the consumed weight was: `pre dispatch weight > consumed
weight > post dispatch weight` then the reclaim code was reducing the
block weight instead of increasing it.

Might explain this issue even better
#5229

This PR adds an additional defensive check to the reclaim SE.

Since it can happen that we miss some storage accesses on other SEs
pre-dispatch, we should double check
that the bookkeeping of the runtime stays ahead of the node-side
pov-size.

If we discover a mismatch and the node-side pov-size is indeed higher,
we should set the runtime bookkeeping to the node-side value. In cases
such as #5229, we would stop including extrinsics and not run `on_idle`
at least.
