KVM: powerpc: Enable commented out BUILD_BUG_ON() assertion

The BUILD_BUG_ON() assertion was commented out in commit 38634e676992
("powerpc/kvm: Remove problematic BUILD_BUG_ON statement") and fixed in
commit c0a187e12d48 ("KVM: powerpc: Fix BUILD_BUG_ON condition"), but
not enabled. Enable it now that this no longer breaks and remove the
comment.
