[PULL 4/5] target/s390x: Fix emulation of C(G)HRL

[Thomas Huth <thuth@redhat.com>]

From: Nina Schoetterl-Glausch <nsg@linux.ibm.com>

The second operand of COMPARE HALFWORD RELATIVE LONG is a signed
halfword, it does not have the same size as the first operand.

Fixes: a7e836d5eb ("target-s390: Convert COMPARE, COMPARE LOGICAL")
