- RtlpInsertFreeBlockHelper: Don't validate the Previous Size of the next Heap Entry when inserting a free Heap Entry into a free list. Should solve bug #5843 and may affect bug #5857.
  All callers of this function already perform this check, except for RtlpInsertFreeBlock, a function used during Heap Segment creation/expansion.
  RtlpInsertFreeBlock creates multiple free Heap Entries (using the helper function) if the free space is too big to be contained in a single Heap Entry.
  In such a case however, it creates a Heap Entry and calls the helper before creating the next Heap Entry, which triggers this assert.
