This change is the echo of your suggestion in
https://patchwork.kernel.org/project/linux-scsi/patch/20200908064507.30774-4-stanley.chu@xxxxxxxxxxxx/

Actually I think your suggestion is constructive that the accepted
values of VS_UNIPROPOWERDOWNCONTROL are better clearly defined so I use
the casting here in this patch.
