Trond Myklebust d5811e6297 NFS: Fix size read races in truncate, fallocate and copy offload ...

If the pre-operation file size is read before locking the inode and
quiescing O_DIRECT writes, then nfs_truncate_last_folio() might end up
overwriting valid file data.

Fixes: b1817b18ff ("NFS: Protect against 'eof page pollution'")
