Fix non matching histogram name.

The histogram is used in NavigationURLLoaderNetworkService as:
Navigation.URLLoaderNetworkService.OnCompleteHadSSLInfo

But it is declared in histograms.xml as:
Navigation.URLLoaderNetworkService.OnCompleteHasSSLInfo

The names don't match ("Had" vs "Has"). This CL fixes it.
