qemu-ga: guest-suspend-hybrid: don't emit a success response
Today, qemu-ga may not be able to emit a success response when
guest-suspend-hybrid completes. This happens because the VM may
suspend before qemu-ga is able to emit a response.
This semantic is a bit confusing, as it's not clear for clients if
they should wait for a response or how they should check for success.
This commit solves that problem by changing guest-suspend-hybrid to
never emit a success response and suggests in the documentation
what clients should do to check for success.
