KVM: MMU: Remove some useless code from alloc_mmu_pages()
If we fail to alloc page for vcpu->arch.mmu.pae_root, call to free_mmu_pages() is unnecessary, which just do free the page malloc for vcpu->arch.mmu.pae_root. Signed-off-by: Wei Yongjun <yjwei@cn.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
