erofs: fix up inplace I/O pointer for big pcluster
When picking up inplace I/O pages, it should be traversed in reverse order in aligned with the traversal order of file-backed online pages. Also, index should be updated together when preloading compressed pages. Previously, only page-sized pclustersize was supported so no problem at all. Also rename `compressedpages' to `icpage_ptr' to reflect its functionality.
