I'll help you here:
Sept/Oct 1938 - Munich Agreement and handing over of the Sudetenland
March 1939 - German occupation of the Czech part of Czecholslovakia, and creation of Slovak state.
August 1939 - Molotov-Ribbentrop Pact
So, as you can see, the non-aggression pact would have had no effect on Czechoslovakia, or Stalin's stance as an ally towards them, as they had ceased to exist 6 months earlier.
