macintosh/therm_windtunnel: fix module unload.
The of_device_unregister call in therm_windtunnel's module_exit procedure
does not fully reverse the effects of of_platform_device_create in the
module_init prodedure. Once you unload this module, it is impossible
to load it ever again since only the first of_platform_device_create
call on the fan node succeeds.
This driver predates first git commit, and it turns out back then
of_platform_device_create worked differently than it does today.
So this is actually an old regression.
The appropriate function to undo of_platform_device_create now appears
to be of_platform_device_destroy, and switching to use this makes it
possible to unload and load the module as expected.
