Could you please clarify in what kind of sequence you were seeing
start_listen getting rejected? The earlier commit
17e20912790a2cca616ddd2856e60e871a377726 ('P2P: Fix radio work
issue with wait-for-peer GO Negotiation') was also addressing a case
that hit this case and I would like to understand whether you are
addressing the same issue or something else.

I'm not completely sure about this change since it is quite different
approach compared to how stop_listen is used currently. As such, I'd
like to understand better the case(s) you are trying to address with
this change.
