thermal: intel: Fix dangling resources on thermal_throttle_online() failure

Browse source

[ Upstream commit b91d287fa7 ]

The function thermal_throttle_add_dev() may fail and abort a CPU hotplug
online operation. Since the failure occurs within the online callback,
thermal_throttle_online(), the CPU hotplug framework does not invoke the
corresponding offline callback. As a result, the hardware and software
resources set up during the failed operation are not torn down.

Since only thermal_throttle_add_dev() can fail, call it before setting up
the rest of the resources.
