Ramaxel inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I4UA67 CVE: NA
----------------------------------------------
Fix: 1.Remove UNF_ORIGIN_HOTTAG_MASK and UNF_HOTTAG_FLAG 2.Update some output string 3.Remove spinlock protect in free_parent_sq() because there is spinlock protect in caller function free_parent_queue_info()
