core/diskboot.inc: fix handover area's sanity checks
As the code operates with paragraph granularity, make sure that
false positives are not possible, though some false negatives
might happen with insanely placed handover area.
Bump low address check to 50h:0, to also avoid bios data area and
remove si == 0 check.
