mds: revoke Fb cap when truncating filewip-truncate
Previous patch makes the filer delete stripe objects that are truncated
to zero. After deleting the objects, OSD can't use truncate seq to detect
old write requests. So we revoke both Fw and Fb caps before truncating a
file, this guarantee that all old write requests are finished.
