Setup the per-CPU SVM data structures at the very end of hardware setup so that svm_hardware_unsetup() can be used in svm_hardware_setup() to unwind AVIC setup (for the GALog notifier). Alternatively, the error path could do an explicit, manual unwind, e.g. by adding a helper to free the per-CPU structures. But the per-CPU allocations have no interactions or dependencies, i.e. can comfortably live at the end, and so converting to a manual unwind would introduce churn and code without providing any immediate advantage.
