Subject: NFS: remove nfs_page_lengthg and usage of page_index
Date: Wed, 22 May 2024 01:58:46 +0800

This function is no longer used after commit 4fa7a717b432 ("NFS: Fix up
nfs_vm_page_mkwrite() for folios"), all users have been converted to use
folio instead, just delete it to remove usage of page_index.
