iio: adc: ad9361: Fix erroneous clearing of the TO_ALERT bit

The TO_ALERT bit should always be set during normal operation. Only intentionally when entering SLEEP or WAIT state we need to clear it. This fixes an issue when in ENSM pin control mode, a calibration is issued, either by changing TX LO > 100MHz or calling any of the manual calibration modes.
