s390/cpcmd: fix inline assembly register clobbering
[ Upstream commit 7a2f9144 ] Register variables initialized using arithmetic. That leads to kasan instrumentaton code corrupting the registers contents. Follow GCC guidlines and use temporary variables for assigning init values to register variables. Fixes: 94c12cc7 ("[S390] Inline assembly cleanup.")
