* Unfortunately a call to IoRegisterFileSystem(), even if followed by a call to
* IoUnregistreFileSystem(), makes the driver unloadable. We attempted to move
* the register/unregister calls to FspFsctlDeviceVolume{Created,Deleted}, but it
* did not make any difference with regards to making the driver unloadable. Hence
* we stick to the simpler scheme of doing registration here.
