KVM: x86/mmu: fix memoryleak in kvm_mmu_vendor_module_init()
When register_shrinker() fails, KVM doesn't release the percpu counter
kvm_total_used_mmu_pages leading to memoryleak. Fix this issue by calling
percpu_counter_destroy() when register_shrinker() fails.
Fixes: ab271bd4dfd5 ("x86: kvm: propagate register_shrinker return code")
