Let's also put the 31-bit hack in front of the REAL MMU, otherwise right now we get errors when loading a PSW where the highest bit is set (e.g. via s390-netboot.img). The highest bit is not masked away, therefore we inject addressing exceptions into the guest. The proper fix will later be to do all address wrapping before accessing the MMU - so we won't get any "wrong" entries in there (which makes flushing also easier). But that will require more work (wrapping in load_psw, wrapping when incrementing the PC, wrapping every memory access). This fixes the tests/pxe-test test.
