[PATCH] thermal/core: Fix double device initialization

[Daniel Lezcano <daniel.lezcano@kernel.org>]

In the previous change splitting the cooling device register function,
the device initialization was mistakenly added in the move.

This change is wrong because the device is registered with the
function device_register() which does device_initialize() and then
device_add(). That results in a double initialization and a message in
logs:

Fix by just removing the added line.
