Net burst fails to clear +L channel redirect mode

[StoneC0ld]

Discovered this by accident...

The ircd does not appear to properly wipe out the +L channel redirect mode during netburst. It appears to the client that it sets -L during the burst, but a /check #channel reveals that +L is still set, and is still active for any client trying to join.

With my services disconnected, I can cycle one of its registered channels and set +L to redirect to another test channel. When I reconnect the services, the net burst deops me (as it should), ops the bot and appears to set -L. However, any client that tries joining the channel still gets redirected, and a /check #channel reveals that +L is still set.

This also happens between client servers. Also, when I'm in the channel on a newer timestamp, I still see -L being set when the services connects, even when +L was never set in the first place.
