From: Junxian Huang <huangjunxian6@hisilicon.com> driver inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICJYA1 ---------------------------------------------------------------------- hr_dev->pgdir_list and hr_dev->pgdir_mutex won't be initialized if CQ/QP record db are not enabled, but they are also needed when using SRQ with SRQ record db enabled. Simplified the logic by initailizing reosurces by default.
