lowlevel-z80: set insys when pre-empting, fix a scribble in some modes

We must update the udata before mapping process memory as we are not
guaranteed that won't vanish the udata.

Set u_insys so that the following case cannot occur once we begin loosening
irq disabled areas

IRQ
pre-empt
ei
swapper()
