iio: imu: inv_icm42600: do not read FIFO count for watermark it

Optimize data reading for high frequencies by not reading FIFO
count in case of watermark interrupt.

We cannot already read more than watermark samples because of the
timestamping mechanism. It is required to not perturb the timing
between the watermark interrupts. Since we also know there is at
least watermark samples in the FIFO, let's just read these watermark
FIFO samples directly without reading FIFO count in this case.
