[PATCH 3.16 211/328] hwmon: (nct6775) Set weight source to zero correctly

From: Dan Carpenter <dan.carpenter@oracle.com>

commit e3f3d7ab00cd459d0f7a839758a4542f4d4b8ac8 upstream.

This is dead code because j can never be 1 at this point. We had
intended to just test if the bit was clear.

Fixes: bbd8decd4123 ("hwmon: (nct6775) Add support for weighted fan control")
