memdisk: move temporary variables away from the EDD data block
Move a couple of variables away from the EDD data block. Without this
change, FreeDOS doesn't boot on Thinkpads. Unfortunately, this should
have been a null change, so it is really not clear why this happens.
Stack overflows have been ruled out. Probably need to examine the
FreeDOS kernel in some detail.
