CreateDevice() implicitly calls WaitForDevice(), which can impact boot time if there are many uevents waiting to be processed. To alleviate this, create an empty "userdata" device when vold starts (if metada encryption is enabled). When it comes time to actually enable metadata encryption, the device can be re-used and the subsequent Wait should be much faster.
