i386: Fix wrong CPU error message in early boot path
- boot/setup.S did not print "PANIC: CPU too old for this kernel"
( not visible, also the message did not match )
- I add "# missed before: set ds"
=> somebody should check if I am right with the way to set.
=> seems to be a generic error in setup.S not to set "ds" for error messages.
AK: extracted patch out of other changes
AK: also couldn't find any other case where ds is wrong
