[Xen-devel][PATCH v3 1/5] sndif: Introduce protocol version

[Oleksandr Andrushchenko <andr2000@gmail.com>]

From: Oleksandr Andrushchenko <oleksandr_andrushchenko@epam.com>

Protocol version was referenced in the protocol description,
but missed its definition. Fix this by adding a constant
for current protocol version.
