P2P: Add a workaround for Extended Listen Timing getting stuck

This should not really happen, but it looks like the Listen command
may fail is something else (e.g., a scan) was running at an
inconvenient time. As a workaround, allow new Extended Listen
operation to be started if this state is detected.
