vhost: Fix vhost_vq_reset()
[ Upstream commit beb691e69f4dec7bfe8b81b509848acfd1f0dbf9 ]
vhost_reset_is_le() is vhost_init_is_le(), and in the case of
cross-endian legacy, vhost_init_is_le() depends on vq->user_be.
vq->user_be is set by vhost_disable_cross_endian().
But in vhost_vq_reset(), we have:
vhost_reset_is_le(vq);
vhost_disable_cross_endian(vq);
And so user_be is used before being set.
To fix that, reverse the lines order as there is no other dependency
between them.
