UsbStorageUnmountter Wakelock Instant Releaser

The Note, S2, S3 and Note 2 all seem to have a lovely bug in which if you unmount a USB stick connected through USB OTG using the what-would-be-normally-convenient-if-it-didn't-expose-a-bug notification, you will be left with a UsbStorageUnmountter wakelock that just won't go until you reboot! jazzk over at XDA put out a fix, which was to stop the wakelock from being created and acquired in the first place, but since I prefer Xposed to working with odexed files, here's a quick conversion.
