P2P: Fix a logical error of workaround of extended listen failure

P2P: Fix a logical error of workaround of extended listen failure

When p2p->state == P2P_LISTEN_ONLY, the statement before it
'p2p->cfg->is_p2p_in_progress(p2p->cfg->cb_ctx)' will be true, too, so
this function will print a message "Operation in progress" and return;
the workaround to handle listen failure will be never reached.

I met such an error when the 'remain-on-channel' command failed, then
the function p2p_ext_listen_timeout() just printed 'Operation in
progress' again and again, and the listen operation was not started
anymore.
