Israel Rukshin 6f7baf41b7 nvme: Fix controller creation races with teardown flow ... [ Upstream commit ce1518139e ] Calling nvme_sysfs_delete() when the controller is in the middle of creation may cause several bugs. If the controller is in NEW state we remove delete_controller file and don't delete the controller. The user will not be able to use nvme disconnect command on that controller again, although the controller may be active. Other bugs may happen if the controller is in the middle of create_ctrl callback and nvme_do_delete_ctrl() starts. For example, freeing I/O tagset at nvme_do_delete_ctrl() before it was allocated at create_ctrl callback. To fix all those races don't allow the user to delete the controller before it was fully created.
