Fixes gcc '-Wunused-but-set-variable' warning:
drivers/hwmon/w83627ehf.c: In function 'w83627ehf_check_fan_inputs':
drivers/hwmon/w83627ehf.c:1296:24: warning:
variable 'fan4min' set but not used [-Wunused-but-set-variable]
commit 62000264cfa8 ("hwmon: (w83627ehf) remove nct6775 and nct6776 support")
left behind this unused variable.
