s390x/kvm: reuse kvm_s390_reset_vcpu() to get rid of ifdefs
This patch reuses kvm_s390_reset_vcpu() to get rid of some CONFIG_KVM and
CONFIG_USER_ONLY ifdefs in cpu.c.
In order to get rid of CONFIG_USER_ONLY, kvm_s390_reset_vcpu() has to provide a
dummy implementation - the two definitions are moved to the proper section in
cpu.h.
