Remove BrowserThread::UI check form GetNetworkServiceFromConnector().

GetNetworkServiceFromConnector() may be called in the early startup before the
full browser starts. Therefore, it can't use
DCHECK_CURRENTLY_ON(content::BrowserThread::UI) to check whether it is called
on the same thread. Instead, we check whether the connector is accessed on the
valid sequence to replace this DCHECK.
