BMP280 sensor is not working with sensortest #8831

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

   ret = ioctl(fd, SNIOC_BATCH, latency);
   if (ret < 0)

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

@xiaoxiang781216 could you please take a look?
