scsi: scsi_ioctl: Drop needless assignment in sg_io()

Commit e7def244f1b8 ("scsi: core: Remove the cmd field from struct
scsi_request") refactored sg_io(), so that it does not allocate directly
and hence does not return -ENOMEM in its error case. That makes a remaining
assignment of -ENOMEM to the return variable needless.

Drop this needless assignment in sg_io().

No functional change. No change in resulting object code.
