platform/chrome: cros_ec_proto: handle empty payload in getting proto info

cros_ec_get_proto_info() expects to receive
sizeof(struct ec_response_get_protocol_info) from send_command().  The
payload is valid only if the return value is positive.

Return -EPROTO if send_command() returns 0 in cros_ec_get_proto_info().
