hwmon: (adm1029) Ensure the fan_div cache is updated in set_fan_div

Browse source

commit 1035a9e3e9 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().
