leds: sgm3140: Add missing timer cleanup and flash gpio control
Enabling strobe and then setting brightness to 0 causes the driver to enter
invalid state after strobe end timer fires. We should cancel strobe mode
resources when changing brightness (aka torch mode).
Fixes: cef8ec8cbd21 ("leds: add sgm3140 driver")
