hwmon: (adm1029) Ensure the fan_div cache is updated in set_fan_div
commit 1035a9e3e9c76b64a860a774f5b867d28d34acc2 upstream.
Writing to fanX_div does not clear the cache. As a result, reading
from fanX_div may return the old value for up to two seconds
after writing a new value.
This patch ensures the fan_div cache is updated in set_fan_div().
