scsi: hisi_sas: relocate clearing ITCT and freeing device
In certain scenarios we may just want to clear the ITCT for a device, and not
free other resources like the SATA bitmap using in v2 hw.
To facilitate this, this patch relocates the code of clearing ITCT from
free_device() to a new hw interface clear_itct(). Then for some hw, we should
not realise free_device() if there's nothing left to do for it.
