[PATCH] iio: pressure: st_pressure_core: disable multiread by default for LPS22HB

[Lorenzo Bianconi]

Set multiread variable to false for LPS22HB pressure sensor since
it is already enabled in CTRL_REG2. Previous configuration does not
cause any issue in I2C communication since SUB Msb has no meaning
whereas it breaks register address in SPI communication

Fixes: e039e2f5b4da (iio:st_pressure:initial lps22hb sensor support)

Applied to the fixes-togreg branch of iio.git and marked for stable.
This will probably only go upstream after the merge window now.
