cpu: call plugin init hook asynchronously
This ensures we run during a cpu_exec, which allows to call start/end
exclusive from this init hook (needed for new scoreboard API introduced
later).
async work is run before any tb is translated/executed, so we can
guarantee plugin init will be called before any other hook.
The previous change made sure that any idle/resume cb call will not be
done before initializing plugin for a given vcpu.
