Try yet again to deal with timing out nodes. We cannot hold the
node lock while sending a management frame as this will potentially
result in a LOR with a driver lock. This doesn't happen for the
Atheros driver but does for the wi driver. Use a generation number
to help process each node once when scanning the node table and
drop the node lock if we need to timeout a node and send a frame.
