[v2] krnl386.exe16: Avoid shift overflows in DMA_ioport_in.

[Gerald Pfeifer]

I believe thisi has been obsoleted by Alexandre's patch

  commit 5767c63ae0edca8635ed70d7071759745997be81
  Author: Alexandre Julliard <julliard at winehq.org>

    krnl386.exe: Remove some redundant shifts.

in case someone is tracking (and since Marvin has not labeled my
patch as rejected so far).
