Christoph Hellwig e9734653c5 fs,fsverity: reject size changes on fsverity files in setattr_prepare ...

Add the check to reject truncates of fsverity files directly to
setattr_prepare instead of requiring the file system to handle it.
Besides removing boilerplate code, this also fixes the complete lack of
such check in btrfs.
