Subject: [PATCH] fs/ntfs3: rename ni_readpage_cmpr into ni_read_folio_cmpr

The old "readpage" naming is still used in ni_readpage_cmpr(), even though
the vfs has transitioned to the folio-based read_folio() API.

This patch performs a straightforward renaming of the helper:
ni_readpage_cmpr() -> ni_read_folio_cmpr().
