[PATCH v4 2/3] iio: adc: ti-ads1298: Fix incorrect timeout comment

[Md Shofiqul Islam <shofiqtest@gmail.com>]

At the lowest supported data rate of 250Hz, one conversion period is
4ms, not 40ms. Fix the comment to correctly reflect the timing.
The 50ms timeout value itself is correct as a conservative margin.
