Subject: [PATCH] virtio/user: fix memory hotplug with the internal rte_vhost
 lib

This was broken in commit 2725b5191e [1], which added
an extra #ifdef SPDK_CONFIG_VHOST_INTERNAL_LIB without
including config.h anywhere within the same file.

Currently the virtio library always behaves as if it was
compiled with upstream rte_vhost. Fix this by including
spdk/config.h where necessary.

[1] virtio/user: don't send SET_VRING_ADDR after updating
    the memory table
