memdisk: don't write the EDD DPT unless we are in EDD mode...

Don't write the EDD DPT unless we're actually in EDD mode!  Otherwise
we end up corrupting memory beyond the defined code.  This was the
reason 5ca2764460883f5e9a5bd83db00f242ea1272e33 worked, by moving
variables out of the corruption zone.
