iio: imu: st_lsm6dsx: fix read misalignment on untagged FIFO
st_lsm6dsx suffers of a read misalignment on untagged FIFO when
all 3 supported sensors (accel, gyro and ext device) are running
at different ODRs (the use-case is reported in the LSM6DSM Application
Note at pag 100).
Fix the issue taking into account decimation factor reading the FIFO
pattern.
