ipvs: Fix race conditions in lblc scheduler
We can't access the cache entry outside of our critical read-locked region, because someone may free that entry. And we also need to check in the critical region wether the destination is still available, i.e. it's not in the trash. If we drop our reference counter, the destination can be purged from the trash at any time. Our caller only guarantees that no destination is moved to the trash, while we are scheduling. Also there is no need for our own rwlock, there is already one in the service structure for use in the schedulers.
