diskio: make maxtransfer per-device, cap to 127, imported from head

Make the maxtransfer per device, as it should be; properly imported
from the head loader (in case it is patched with -s).  Also enforce
capping to 127 for EBIOS and 63 for CBIOS.  This is structured so that
once EDD4 is approved we can remove the capping for that particular
subcase.
