commit 2751c9882b947292fcfb084c4f604e01724af804 ("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.

Michael, do you want me to take this via the 'net' tree?

Sure - especially since it looks like I have nothing else for this merge
window (working on fixing shutdown races, but it's slow going).  Thanks
a lot!
