P2P: Do not allow pending listen command override connect

If p2p_listen is issued during a p2p_scan, a pending after-scan operation
is scheduled. However, since there is support for only a single pending
operation, this was able to override a previously scheduled pending
connect command. This can break some command sequences, so give higher
priority to pending connect operation.
