[media] rc: ite-cir: fix potential double free in ite_probe()
Since rc_unregister_device() frees its argument, the subsequently call to rc_free_device() on the same variable will cause a double free bug. Fix by set argument to NULL, thus when fall through to rc_free_device(), nothing will be done there.
