Michael S. Tsirkin e407f39afd vhost: fix performance on LE hosts
commit 2751c9882b ("vhost: cross-endian
support for legacy devices") introduced a minor regression: even with
cross-endian disabled, and even on LE host, vhost_is_little_endian is
checking is_le flag so there's always a branch.

To fix, simply check virtio_legacy_is_little_endian first.
