erofs: rework online page handling

Since all decompressed offsets have been integrated to bvecs[], this
patch avoids all sub-indexes so that page->private only includes a
part count and an eio flag, thus in the future folio->private can have
the same meaning.

In addition, PG_error will not be used anymore after this patch and
we're heading to use page->private (later folio->private) and
page->mapping  (later folio->mapping) only.
