Halil Pasic 70a6dadf36 s390/ap: fix status returned by ap_qact() 
[ Upstream commit a2522c80f0 ]

Since commit 159491f3b5 ("s390/ap: rework assembler functions to use
unions for in/out register variables") the  function ap_qact() tries to
grab the status from the wrong part of the register. Thus we always end
up with zeros. Which is wrong, among others, because we detect failures
via status.response_code.
