KVM: s390: Don't indicate suppression on dirtying, failing memop

If user space uses a memop to emulate an instruction and that
memop fails, the execution of the instruction ends.
Instruction execution can end in different ways, one of which is
suppression, which requires that the instruction execute like a no-op.
A writing memop that spans multiple pages and fails due to key
protection may have modified guest memory, as a result, the likely
correct ending is termination. Therefore, do not indicate a
suppressing instruction ending in this case.
