hwmon: (adt7462) Fix an error return in ADT7462_REG_VOLT()

This is only called from adt7462_update_device().  The caller expects it
to return zero on error.  I fixed a similar issue earlier in commit
a4bf06d58f21 ("hwmon: (adt7462) ADT7462_REG_VOLT_MAX() should return 0")
but I missed this one.

Fixes: c0b4e3ab0c76 ("adt7462: new hwmon driver")
