[PATCH next] iio: adc: qcom-spmi-adc5-gen3: Fix off by one in adc5_gen3_get_fw_channel_data()

[Dan Carpenter]

The > in "if (chan > ADC5_MAX_CHANNEL)" should be >= to prevent an out
of bound read of the adc->data->adc_chans[] array.

Fixes: baff45179e90 ("iio: adc: Add support for QCOM PMIC5 Gen3 ADC")
