target/s390x: Fix CLC corrupting cc_src
CLC updates cc_src before accessing the second operand; if the latter
is inaccessible, the former ends up containing a bogus value.
Fix by reading cc_src into a temporary first.
Fixes: 4f7403d52b1c ("target-s390: Convert CLC")
Closes: https://gitlab.com/qemu-project/qemu/-/issues/1865
