Xiang Chen 3e178f3ecf scsi: hisi_sas: Free slot later in slot_complete_vx_hw() ... If an SSP/SMP IO times out, it may be actually in reality be simultaneously processing completion of the slot in slot_complete_vx_hw(). Then if the slot is freed in slot_complete_vx_hw() (this IPTT is freed and it may be re-used by other slot), and we may abort the wrong slot in hisi_sas_abort_task(). So to solve the issue, free the slot after the check of SAS_TASK_STATE_ABORTED in slot_complete_vx_hw().
