In commit af6bf1328e (May 2011),
ide-hd, ide-cd and scsi-cd have been added to disable default cdrom,
"or else you can't put one on secondary master without -nodefaults".
Make it the same for scsi-hd, so you can put one on scsi-id 2 without
using -nodefaults.
scsi-hd has probably been forgotten, as it has been added in the
preceding commit (b443ae6713).
Affected users are the ones using a machine with SCSI devices and start QEMU
with -device scsi-hd but without -device scsi-cd or -cdrom
In that case, the default cdrom device will disappear instead of being empty.
