afs: drop usage of folio_file_pos

Browse Source 
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 mapping may only call into fs
through swap_rw and that is not supported for afs.  So just drop it and
use folio_pos instead.
