Log:
client.c: fix up return value from CIF call-method/interpret

The handle_calls() function was accidentally using the client-call-iface return
value instead of the catch wrapping the underlying call.

Return the correct catch result, and while we're at it add some extra logging
to indicate when we've detected an error condition.
