[PATCH v3 06/12] afs: drop usage of folio_file_pos

[Kairui Song]

From: Kairui Song <kasong@xxxxxxxxxxx>

folio_file_pos is only needed for mixed usage of page cache and
swap cache, for pure page cache usage, the caller can just use
folio_pos instead.

It can't be a swap cache page here, swap cache is never exposed
to afs, so just drop it and use folio_pos instead.
