Subject: iio: trigger: stm32-timer: fix a corner case to write preset

From: Fabrice Gasnier <[email protected]>

commit b7a9776c1f9443326632486fcbd82dca82f8511e upstream.

Balance timer start routine that sets ARPE: clear it in stop routine. This fixes a corner case, when timer is used successively as trigger (with sampling_frequency start/stop routines), then as a counter (with preset).
