dlm: keep cached master rsbs during recovery
To prevent the master of an rsb from changing rapidly, an unused rsb is kept on the "toss list" for a period of time to be reused. The toss list was being cleared completely for each recovery, which is unnecessary. Much of the benefit of the toss list can be maintained if nodes keep rsb's in their toss list that they are the master of. These rsb's need to be included when the resource directory is rebuilt during recovery. Signed-off-by: David Teigland <teigland@redhat.com>
