1. mds: just wait the client flushes the snap and dirty buffer …

   When truncating the inode we will just set the ifile lock state to
   LOCK_XLOCKSNAP and then try to revoke the 'Fb' caps, but if the
   client couldn't release the 'Fb' cap in time just replies with a
   normal cap updating request, the MDS will successfully transfer
   the ifile's lock state to LOCK_EXCL, which is stable.
   
   That means the MDS will wake up the truncating request and continue
   truncating the objects from Rados without waiting the clients to
   flush the diry buffer.
   
   Fixes: commit 9c65920 ("mds: force client flush snap data before
   		truncating objects")
