[S390] Misaligned wait PSW at memory detection.

If the memory detection code would ever reach the point where it would
load the wait psw, it would generate a specification exception and the
system would crash at ipl time. This is because of a misaligned wait
psw. It needs to be on a double word boundary instead of a word
boundary.
