Subject: [PATCH] drivers: hwmon: pwm-fan: fix warning unused variable 'ctx'

When building hwmon/pwm-fan the following unused-variable warning shows
up:

/tmp/drivers/hwmon/pwm-fan.c: In function ‘pwm_fan_is_visible’:
/tmp/drivers/hwmon/pwm-fan.c:167:22: warning: unused variable ‘ctx’ [-Wunused-variable]

Remove the unneeded variable declaration 'ctx'.

Fixes: 439ed83acc19 ("hwmon: (pwm-fan) Convert to hwmon_device_register_with_info API")
