thermal/drivers/qcom: Remove duplicate set next trip point interrupt code

From: Daniel Lezcano <daniel.lezcano@linaro.org>

The tsens driver reprogram the next trip points in the irq
handler. This function then call thermal_zone_device_update().

However, thermal_zone_device_update() calls thermal_zone_set_trips()
and from there it calls the backend 'set_trips' ops. This one in turn
reprogram the next trip points (low/high).

Consequently, the code setting the next trip points interrupt in the
interrupt handle is not needed and could be removed.

Thanks for the review. I'll remove the duplicated SoB.
