[PATCH 4/8] ceph: drop usage of page_index

[Kairui Song <ryncsn@gmail.com>]

From: Kairui Song <kasong@tencent.com>

page_index is needed for mixed usage of page cache and swap cache,
for pure page cache usage, the caller can just use page->index instead.

It can't be a swap cache page here, so just drop it.
