[lm-sensors] [PATCH] hwmon: fix dme1737 temp fault attribute

[Mark M. Hoffman]

From: Juerg Haefliger <juergh at gmail.com>

Fix temp?_fault attribute. The temp was incorrectly compared against
0x0800 rather than 0x8000. Only the upper 8 bits are compared as the
datasheet doesn't specify what happens to the lower bits in case of a
diode fault.
