scsi: hisi_sas: fix a bug in hisi_sas_dev_gone()
When device gone, NULL pointer can be accessed in free_device callback
if during SAS controller reset as we clear structure sas_dev prior.
Actually we can only set dev_type as SAS_PHY_UNUSED and not clear
structure sas_dev as all the members of structure sas_dev will be
re-initialized after device found.
