Adding the destroy_workqueue call in i3c_master_register introduced below kernel warning because it makes duplicate destroy_workqueue calls when i3c_master_register fails after allocating the workqueue. The workqueue will be destroyed by i3c_masterdev_release which is called by put_device at the end of the i3c_master_register function eventually in failure cases so the workqueue doesn't need to be destroyed in i3c_master_register.
