hisi_hba->timer is not used for v3 hw but there are two places that some operations related to hisi_hba->timer are called by v3 hw: - Deleting the timer in function hisi_sas_v3_hw() which is only for v3 hw; - Deleting the timer in function hisi_sas_controller_reset_prepare() which is common for v1/v2/v3 hw. We can remove the timer in the first case, but for the second scenario we need to remove it only for v3 hw, so check hw->sht which is NULL only for v3 hw before deleting hisi_hba->timer.
