hwmon: (w83791d) Fix smatch warning

smatch complains as follows when checking w83791d.c.

drivers/hwmon/w83791d.c:996 store_temp23() warn:
'32768' 32768 can't fit into 32767 'data->temp_add[nr][index]'

Fix by using DIV_ROUND_CLOSEST and clamp_val to convert the values.
While we are at it, modify other macros as well for consistency and
to make the code easier to understand.
