KVM: s390: Stop using CONFIG_PGSTE

Browse Source 
Switch to using IS_ENABLED(CONFIG_KVM) instead of CONFIG_PGSTE, since
the latter will be removed soon.

Many CONFIG_PGSTE are left behind, because they will be removed
completely in upcoming patches. The ones replaced here are mostly the
ones that will stay.
