[Cluster-devel] [PATCH 4/4] dlm: use bastmode in debugfs output

The bast mode that appears in the debugfs output should be
useful on both master and process nodes.  lkb_highbast is
currently printed, and is only useful on the master node.
lkb_bastmode is only useful on the process node.  This
patch sets lkb_bastmode on the master node as well, and
uses that value in the debugfs print.
