netfs: Fix netfs_release_folio() to say no if folio dirty
Fix netfs_release_folio() to say no (ie. return false) if the folio is
dirty (analogous with iomap's behaviour). Without this, it will say yes to
the release of a dirty page by split_huge_page_to_list_to_order(), which
will result in the loss of untruncated data in the folio.
Without this, the generic/075 and generic/112 xfstests (both fsx-based
tests) fail with minimum folio size patches applied[1].
Fixes: c1ec4d7c2e13 ("netfs: Provide invalidate_folio and release_folio calls")
