Do this by: - Removing more instances of `LockRefPtr` and `NonnullLockRefPtr`. - Using better names of construction methods (i.e. `create` instead of `try_create`). - Only returning `NonnullRefPtr` on the `Device::try_create_device` method. - Removing a version of the `Device::try_create_device` method that called `DeviceType::try_create(forward<Args>(args)...)`, which was only used in a construction point in a VirtIO driver which now doesn't need this anymore.
