scsi: sg: Re-fix off by one in sg_fill_request_table()
Commit 109bade9c625 ("scsi: sg: use standard lists for sg_requests") introduced an off-by-one error in sg_ioctl(), which was fixed by commit bd46fc406b30 ("scsi: sg: off by one in sg_ioctl()"). Unfortunately commit 4759df905a47 ("scsi: sg: factor out sg_fill_request_table()") moved that code, and reintroduced the bug (perhaps due to a botched rebase). Fix it again.
