Subject: [PATCH] hwmon: (aquacomputer_d5next) Fix Quadro fan speed offsets

The offsets for setting speeds of fans connected to Quadro are off by one.
Set them to their correct values.

The offsets as shown point to registers for setting the fan control mode,
which will be explored in future patches, but slipped in here. When
setting fan speeds, the resulting values were overlapping, which made the
fans still run in my initial testing.
