target/s390x: fix IPM polluting irrelevant bits
Suppose psw.mask=0x0000000080000000, cc=2, r1=0 and we do "ipm 1".
This command must touch only bits 32-39, so the expected output
is r1=0x20000000. However, currently qemu yields r1=0x20008000,
because irrelevant parts of PSW leak into r1 during program mask
transfer.
