memory: Fix old_portio vs non-zero offset
The legacy functions that we're wrapping expect that offset to be included in the register. Indeed, they generally expect the absolute address and then mask off the "high" bits. The FDC is the first converted device with a non-zero offset. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Avi Kivity <avi@redhat.com>
