Fix chunk_unmap() to propagate dirty state.
Fix chunk_unmap() to propagate whether a chunk is dirty, and modify
dirty chunk purging to record this information so it can be passed to
chunk_unmap(). Since the broken version of chunk_unmap() claimed that
all chunks were clean, this resulted in potential memory corruption for
purging implementations that do not zero (e.g. MADV_FREE).
This regression was introduced by
ee41ad409a43d12900a5a3108f6c14f84e4eb0eb (Integrate whole chunks into
unused dirty page purging machinery.).
