hwmon: (nct7802) Fix wrong detection of in4 presence
commit 38ada2f406a9b81fb1249c5c9227fa657e7d5671 upstream.
The code to detect if in4 is present is wrong; if in4 is not present,
the in4_input sysfs attribute is still present.
In detail:
- Ihen RTD3_MD=11 (VSEN3 present), everything is as expected (no bug).
- If we have RTD3_MD!=11 (no VSEN3), we unexpectedly have a in4_input
file under /sys and the "sensors" command displays in4_input.
But as expected, we have no in4_min, in4_max, in4_alarm, in4_beep.
Fix is_visible function to detect and report in4_input visibility
as expected.
