use channel_is_client for create cell counts

Browse Source 
When a relay is collecting internal statistics about how many
create cell requests it has seen of each type, accurately count the
requests from relays that temporarily fall out of the consensus.

(To be extra conservative, we were already ignoring requests from clients
in our counts, and we continue ignoring them here.)

Fixes bug 24910; bugfix on 0.2.4.17-rc.
