It only allows to audit one guest in the system since:
- 'audit_point' is a glob variable
- mmu_audit_disable() is called in kvm_mmu_destroy(), so audit is disabled
after a guest exited
this patch fix those issues then allow to audit more guests at the same time

Can't you free and reallocate all guest memory instead, on reboot, if
there's a hwpoisoned page? Then you don't need this interface.
I think that would be more efficient. You can potentially save a lot
of memory if the new guest doesn't need as much as the old one.
