Windows: Promote DELETED from DirEntry to ObjInfo

Windows: Promote DELETED from DirEntry to ObjInfo

On deletion of the DirEntry in AFSDeleteDirEntry() set the
AFS_OBJECT_FLAGS_DELETED flag on the ObjectInformation object
if and only if the AFS_DIR_ENTRY_DELETED flag was set in the
DirEntry.  Setting the AFS_OBJECT_FLAGS_DELETED should not
be conditional on the ObjectInformatION ReferenceCount being
zero.

Remove the test and set of AFS_OBJECT_FLAGS_DELETED from
AFSClose() because that operation will already have been
performed in the call to AFSDeleteDirEntry() if necessary.
