sorry, but you can't disable the BGP scanner. It runs as a low-prio
task, so anything more urgent to take care of gets done..
In the upcoming 12.3(14)T release, we made BGP NH tracking event-driven
("BGP Support for Next-Hop Address Tracking", already shipping in
12.0(29)S, will also be in 12.2S later), so BGP scanner will no longer
be needed for this..
