hwmon: (w83l786ng) Fix fan speed control mode setting and reporting
commit cf7559bc053471f32373d71d04a9aa19e0b48d59 upstream.
The wrong mask is used, which causes some fan speed control modes
(pwmX_enable) to be incorrectly reported, and some modes to be
impossible to set.
[JD: add subject and description.]
