Add a helper that allocates the nvme_dev structure up to the point where we can call nvme_init_ctrl. This pairs with the free_ctrl method and can thus be used to cleanup the teardown path and make it more symmetric. Note that this now calls nvme_init_ctrl a lot earlier during probing, which also means the per-controller character device shows up earlier. Due to the controller state no commnds can be send on it, but it might make sense to delay the cdev registration until nvme_init_ctrl_finish.
