nfs: introduce nfs_release_request_list helper
Introduce a centralized helper, nfs_release_request_list, to handle
the bulk release of nfs_page requests from a list.
This serves as a preparatory step for two upcoming improvements:
1. Pin-Aware Cleanup: As we migrate to iov_iter_extract_* API,
requests will hold pins (GUP) instead of standard references. The
helper ensures that the correct unpinning logic gets applied
consistently across all requests in a list.
2. Folio Support: In subsequent patches where nfs_page structures
will cover multi-page folios, this helper provides a clean
infrastructure to unlock these larger units of I/O in bulk during
completion, similar to the pattern in bio_release_pages.
Additionally, refactor nfs_read_sync_pgio_error() to utilize this new
helper.
