Empty rehashing list in emptyDbStructure (#12764) 

This is currently harmless, since we have already cleared the dict
before, it will reset the rehashidx to -1, and in incrementallyRehash
we will call dictIsRehashing to check.

It would be nice to empty the list to avoid meaningless attempts, and
the code is also unified to reduce misunderstandings.
