ocfs2: Fix a race in o2dlm lockres mastery
In o2dlm, the master of a lock resource keeps a map of all interested
nodes. This prevents the master from purging the resource before an
interested node can create a lock.
A race between the mastery thread and the mastery handler allowed an
interested node to discover who the master is without informing the
master directly. This is easily fixed by holding the dlm spinlock a
little longer in the mastery handler.
