hmi-controller: Do not call hmi_controller_destroy() from _create()

Move the destroy listener registration to the top, to avoid having to call hmi_controller_destroy() for cleanup when it

This would segfault trying to remove the uninitialized destroy listener from a list it was never added to.

The failure case can be hit by setting both modules=hmi-controller.so in weston.ini and --modules=hmi-controller.so on the command line.
