stable inclusion from stable-v5.10.121 commit 02192ee93684e2989ec359821bc91850a3c46d5e category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6CQ

--------------------------------
[ Upstream commit bee40dc167da159ea5b939c074e1da258610a3d6 ]
Clearing hba->is_sys_suspended if ufs_qcom_resume() succeeds is wrong. That variable must only be cleared if all actions involved in a resume succeed. Hence remove the statement that clears hba->is_sys_suspended from ufs_qcom_resume().
