wifi: mac80211: mesh: don't send peering close in listen

Browse Source 
In listen state, nothing has been sent, so there's no
need to send a WLAN_SP_MESH_PEERING_CLOSE frame. Also,
in case the station just failed to insert, e.g. due
to a missing channel context, it might not be possible
to transmit the frame at all, leading to a warning.
