Subject: scsi: fas216: Stop using scsi_cmnd.scsi_done
Git-commit: 696fec18e17cb63d480e29aafc39d273bd9b776d
Patch-mainline: v5.16-rc1
References: jsc#PED-1561

Store the completion callback pointer in struct fas216_cmd_priv instead of
in struct scsi_cmnd. This patch prepares for removal of the scsi_done
member from struct scsi_cmnd.
