This patch fixes two problems in dlm_run_purgelist 1. If a lockres is found to be in use, dlm_run_purgelist keeps trying to purge the same lockres instead of trying the next lockres. 2. When a lockres is found unused, dlm_run_purgelist releases lockres spinlock before setting DLM_LOCK_RES_DROPPING_REF and calls dlm_purge_lockres. spinlock is reacquired but in this window lockres can get reused. This leads to BUG. This patch modifies dlm_run_purgelist to skip lockres if it's in use and purge next lockres. It also sets DLM_LOCK_RES_DROPPING_REF before releasing the lockres spinlock protecting it from getting reused.
