[PATCH] thermal/core: Remove pointless variable when registering a cooling device

[Daniel Lezcano]

From: Daniel Lezcano <daniel.lezcano@xxxxxxxxxxxxxxxx>

The 'id' variable is set to store the ida_alloc() value which is
already stored into cdev->id. It is pointless to use it because
cdev->id can be used instead.
