KVM: s390: Improve kvm_s390_vm_stop_migration()

There is no need to clear cmma-dirty state if the VM is not using CMMA.

Skip the CMMA-related code if CMMA is not in use.

Fixes: 6cfd47f91f6a ("KVM: s390: Fix cmma dirty tracking")
Fixes: 190df4a212a7 ("KVM: s390: CMMA tracking, ESSA emulation, migration mode")
