iio: imu: inv_icm42600: fix odr switch to the same value

ODR switch is done in 2 steps when FIFO is on : change the ODR register
value and acknowledge change when reading the FIFO ODR change flag.
When we are switching to the same odr value, we end up waiting for a
FIFO ODR flag that is never happening.

Fix the issue by doing nothing and exiting properly when we are
switching to the same ODR value.
