qca-wifi: Handle capture interval and capture duration for RCC

FW may limit the interval and duration during which HW may
use user provided values and attempt to capture.
These values range from 1 us to roughly 16.8 sec.
Max value is 0xFFFFFF which is 16.777215 sec.

Add check to make sure that capture duration cannot exceed
capture interval.
