ipvs: fix dst_lock locking on dest update

commit ff75f40f44ae9b79d520bf32a05d35af74a805c0 upstream.

	Fix dst_lock usage in __ip_vs_update_dest. We need
_bh locking because destination is updated in user context.
Can cause lockups on frequent destination updates.
Problem reported by Simon Kirby. Bug was introduced
in 2.6.37 from the "ipvs: changes for local real server"
change.
