Guard guest prefix handling behind `KVM_S390_MANAGES_S390_GUEST`. This
enables other KVM implementations to use gmap without implementing
prefix handling. The prefix handling is integrated deeply in the gmap
implementation. Therefore, provide safe default implementations for the
guarded functions.

No functional changes.
