Xue jiufei ac4fef4d23 ocfs2/dlm: do not purge lockres that is queued for assert master ... When workqueue is delayed, it may occur that a lockres is purged while it is still queued for master assert. it may trigger BUG() as follows. N1 N2 dlm_get_lockres() ->dlm_do_master_requery is the master of lockres, so queue assert_master work dlm_thread() start running and purge the lockres dlm_assert_master_worker() send assert master message to other nodes receiving the assert_master message, set master to N2 dlmlock_remote() send create_lock message to N2, but receive DLM_IVLOCKID, if it is RECOVERY lockres, it triggers the BUG(). Another BUG() is triggered when N3 become the new master and send assert_master to N1, N1 will trigger the BUG() because owner doesn't match. So we should not purge lockres when it is queued for assert master.
