[PATCH v13 07/23] fs,fsverity: remove check for fsverity being enabled in setattr_prepare()

The check that fs-verity is available in the kernel is not necessary
here. Filesystems could have fsverity files even without fs-verity
module, then truncate will succeed. Previously, this would return
EOPNOTSUPP if verity is missing, but if it's not EPERM was returned
anyway.
