Windows: Improve AFSNotifyDelete

Do not call AFSNotifyDelete after the reference count on the
DirEntry->ObjectInformation is given up.

Log the Parent FID and file name since that is what are passed
to the service to perform a  delete.  Log the actual FID of the
object being deleted and not the address of the FID fields.
