A new function _kvm_s390_real_to_abs will apply prefixing to a real address
with a given prefix value.
The old kvm_s390_real_to_abs becomes now a wrapper around the new function.
This is needed to avoid code duplication in vSIE.

Just a matter of taste, but maybe this could be named differently?
kvm_s390_real2abs_prefix() ? kvm_s390_prefix_real_to_abs()?

+1, I also dislike these "_.*" style functions here.
