This bug was initially created as a copy of Bug #2227997

I am copying this bug because: 



In case:

           mds                             client
                                - Releases cap and put Inode
  - Increase cap->seq and sends
    revokes req to the client
  - Receives release req and    - Receives & drops the revoke req
    skip removing the cap and
    then eval the CInode and
    issue or revoke caps again.
                                - Receives & drops the caps update
                                  or revoke req
  - Health warning for client
    isn't responding to
    mclientcaps(revoke)
All the IMPORT/REVOKE/GRANT cap ops will increase the session seq
in MDS side and then the client need to issue a cap release to
unblock MDS to remove the corresponding cap to unblock possible
waiters.
