BMP280 sensor is not working with sensortest

I noticed that sensortest is not working with BMP280 sensor

How to test:

1) connect a BMP280 module to I2C pins 22 and 23 of ESP32-Devkitc
2) run: $ ./tools/configure.sh esp32-devkitc:bmp280
3) run: $ make flash ESPTOOL_PORT=/dev/ttyUSB1 -j

Use minicom or other serial console and run:

```
nsh> ls /dev
/dev:
console
i2c0
kmsg
null
ttyS0
uorb/

nsh> ls /dev/uorb
/dev/uorb:
sensor_baro0

nsh> sensortest baro0
sensor_ioctl: cmd=a81 arg=000f4240
bmp280_set_standby: Failed to set value for standby time.
Failed to set interval for sensor:/dev/uorb/sensor_baro0, ret:Unknown error
```

I confirmed that commenting these lines solves the issue:

```
diff --git a/testing/sensortest/sensortest.c b/testing/sensortest/sensortest.c

```

Then running the above command again I can see the pressure and temperature changing:
```
