[PATCH 5.17 302/772] scsi: ufs: qcom: Fix ufs_qcom_resume()

From: Bart Van Assche <bvanassche@acm.org>

[ 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().
