Subject: [PATCH v2 28/50] KVM: s390: Mark __kvm_s390_init() and its
 descendants as __init

Tag __kvm_s390_init() and its unique helpers as __init.  These functions
are only ever called during module_init(), but could not be tagged
accordingly while they were invoked from the common kvm_arch_init(),
which is not __init because of x86.
