[Qemu-devel] [PULL 17/28] hw/virtio: Fix brace Werror with clang 6.0.0

["Michael S. Tsirkin" <mst@redhat.com>]

From: Richard Henderson <richard.henderson@linaro.org>

The warning is

hw/virtio/vhost-user.c:1319:26: error: suggest braces
      around initialization of subobject [-Werror,-Wmissing-braces]
    VhostUserMsg msg = { 0 };
                         ^
                         {}

While the original code is correct, and technically exactly correct
as per ISO C89, both GCC and Clang support plain empty set of braces
as an extension.
