[PATCH] KVM: fix build warning within __kvm_set_memory_region() on s390

From: Heiko Carstens <heiko.carstens@de.ibm.com>

Get rid of this warning:

CC arch/s390/kvm/../../../virt/kvm/kvm_main.o
arch/s390/kvm/../../../virt/kvm/kvm_main.c:596:12: warning: 'kvm_create_dirty_bitmap' defined but not used

The only caller of the function is within a !CONFIG_S390 section, so add the
same ifdef around kvm_create_dirty_bitmap() as well.
