Windows: Invalidate all volumes at library init

Browse Source 
The afsredirlib.sys library driver is unloaded when the afsd_service
stops and is reloaded when the afsd_service restarts.  During the
shutdown window any objects known to the kernel are preserved by
afsredir.sys.  When the afsd_service restarts, there are no valid
callbacks on any objects so the afsredirlib.sys must invalidate all
status info to permit the service to request a callback from the
file server on next use.
