P2P: Fix disallowing of pending listen command to override connect

P2P: Fix disallowing of pending listen command to override connect

Commit d9bdba9f867577ed9da6df9c5c933033c71bcdf2 was supposed to allow
p2p_listen to schedule new after scan operation only if a p2p_connect
operation was not pending. However, it used incorrect P2P_AFTER_SCAN_
value for this and did not actually prevent overriding of p2p_connect
and could have caused some p2p_listen operations to be skipped
unnecessarily.
