[LU-9997] Suspicious assert check in ldlm_cli_cancel

Related — Tue, 19 Dec 2017 21:32:52 +0000

The assert in ldlm_cli_cancel() seems to be problematic:

        /* Even if the lock is marked as LDLM_FL_BL_AST, this is a LDLM_CANCEL  
         * RPC which goes to canceld portal, so we can cancel other LRU locks   
         * here and send them all as one LDLM_CANCEL RPC. */                    
        LASSERT(list_empty(&lock->l_bl_ast));                                   
        list_add(&lock->l_bl_ast, &cancels);

because the lock may have been picked up LRU and added into canceling list.
