bmi3_extract_temperature and bmi3_extract_gyro bad operation ordering

[AustinJ755]

In bmi3_extract_temperature and bmi3_extract_gyro the data_index is first updated conditionally and then the index is checked using check_data_index. This is incorrect as check_data_index also updates the data_index for it's check causing it to fail even when there is a frame the code is capable of reading.

Therefore the following

if (fifo->available_fifo_sens & BMI3_FIFO_HEAD_LESS_ACC_FRM)
{
    data_index = data_index + BMI3_LENGTH_FIFO_ACC;
}
rslt = check_data_index(data_index, fifo);

should change to

rslt = check_data_index(data_index, fifo);
if (fifo->available_fifo_sens & BMI3_FIFO_HEAD_LESS_ACC_FRM)
{
    data_index = data_index + BMI3_LENGTH_FIFO_ACC;
}
