Subject: [PATCH] thermal: fix thermal_zone_bind_cooling_device prototype

When the prototype for thermal_zone_bind_cooling_device
changed, the static inline wrapper function was left alone,
which in theory can cause build warnings:

I have seen this error in the past:
drivers/thermal/db8500_thermal.c: In function 'db8500_cdev_bind':
drivers/thermal/db8500_thermal.c:78:9: error: too many arguments to function 'thermal_zone_bind_cooling_device'
ret = thermal_zone_bind_cooling_device(thermal, i, cdev,

while this one no longer shows up, there is no doubt that
the prototype is still wrong, so let's just fix it anyway.

Yes, we forgot to fix the case for !THERMAL
