iio: imu: inv_mpu6050: fix FIFO parsing when empty

Browse source

Now that we are reading the full FIFO in the interrupt handler,
it is possible to have an emply FIFO since we are still receiving
1 interrupt per data. Handle correctly this case instead of having
an error causing a reset of the FIFO.
