[PATCH] iio: st_sensors: Fix the sleep time for sampling

[Jian-Hong Pan]

According to the description of st_sensor_settings and st_sensor_data
structures' comments:
- bootime: samples to discard when sensor passing from power-down to
power-up.
- odr: Output data rate of the sensor [Hz].

The sleep time should be
sdata->sensor_settings->bootime + 1000 / sdata->odr ms.
