Alas, even with this change, on NetBSD 10 (haven't yet tried booting
with -current), it's still insufficient for the disks on the same
target from attaching except for the first one; they do still show
up in `scsictl sd0 reportluns all`, though - four on one target,
eight on the other.

It *does* work in -current for me as well, so I'll take that as a win.
