Subject: [PATCH] CLIENT KILL: don't kill the master as a normal client.

Technically the problem is due to the client type API that does not
return a special value for the master, however fixing it locally in the
CLIENT KILL command is better currently because otherwise we would
introduce a new output buffer limit class as a side effect.
