memdisk: Restore DL for INT 13h, AH=15h, DL=floppysyslinux-3.84-pre4
At least PC-DOS requires this to avoid an infinite loop; the DL we
restore is not the same DL that we call the underlying BIOS with, but
rather the original one (before the decrement.) PC-DOS loops over all
the floppies and relies on the call preserving DL in order to advance
the loop.
