piaojun 60c7ec9ee4 ocfs2/dlm: wait for dlm recovery done when migrating all lock resources
Wait for dlm recovery done when migrating all lock resources in case that
new lock resource left after leaving dlm domain.  And the left lock
resource will cause other nodes BUG.

        NodeA                       NodeB                NodeC

  umount:
    dlm_unregister_domain()
      dlm_migrate_all_locks()

                                   NodeB down

  do recovery for NodeB
  and collect a new lockres
  form other live nodes:

    dlm_do_recovery
      dlm_remaster_locks
        dlm_request_all_locks:

    dlm_mig_lockres_handler
      dlm_new_lockres
        __dlm_insert_lockres

  at last NodeA become the
  master of the new lockres
  and leave domain:
    dlm_leave_domain()

                                                    mount:
                                                      dlm_join_domain()

                                                    touch file and request
                                                    for the owner of the new
                                                    lockres, but all the
                                                    other nodes said 'NO',
                                                    so NodeC decide to be
                                                    the owner, and send do
                                                    assert msg to other
                                                    nodes:
                                                    dlmlock()
                                                      dlm_get_lock_resource()
                                                        dlm_do_assert_master()

                                                    other nodes receive the msg
                                                    and found two masters exist.
                                                    at last cause BUG in
                                                    dlm_assert_master_handler()
                                                    -->BUG();
