[PATCH 10/14] target/s390x: Raise exception from per_store_real


From: Richard Henderson
Subject: [PATCH 10/14] target/s390x: Raise exception from per_store_real
Date: Wed, 1 May 2024 22:44:13 -0700

At this point the instruction is complete and there's nothing
left to do but raise the exception.  With this change we need
not make two helper calls for this event.
