DatabaseShardingState::checkDbVersion is normally called in DBLock, which AutoGetCollectionLFR will not use. I think we'll want to perform the check after setting up consistent catalog state (opening a storage snapshot), but need to prove it first in SERVER-51274
Also remove the dassert lock checks in DatabaseShardingState::get() and CollectionShardingState::get() in this task.
