[PATCH] P2P: Include passive channels in invitation response

Patch 51e9f22809b0f412c9c10baa34ddc46cf5df4f33 added the option
p2p_add_cli_chan to allow P2P GC to connect on passive channels
assuming the GO should know whether allowed to send on these channels.
This patch adds missing cli_channels to invitation response messages
to allow re-connecting to a persistent group as GC on passive
channels.
