Hi,
This series failed the docker-quick@centos7 build test. Please find the testing commands and
their output below. If you have Docker installed, you can probably reproduce it
locally.

The previous wording was (at least to me) ambiguous about whether a backend should enable features immediately after they were set using VHOST_USER_SET_PROTOCOL_FEATURES, or wait for support for protocol features to be acknowledged if it hasn't been yet before enabling those features. This patch attempts to make it clearer that VHOST_USER_SET_PROTOCOL_FEATURES should immediately enable features, even if support for protocol features has not yet been acknowledged, while still also making clear that the frontend SHOULD acknowledge support for protocol features.
