[0/2] KVM: CPUID: CPUID emulation flow adjustment and one minor refinement when updating maxphyaddr

Message

Patch 1 adjusts the execution flow of CPUID instruction emulation, which
checks the leaf number first per CPUID specification.

Patch 2 moves physical address width updating to where we check the virtual
address width in function kvm_update_cpuid() since they two use the same
cpuid leaf, which makes it more reasonable and no functional change.  

Xiaoyao Li (2):
  KVM: CPUID: Check limit first when emulating CPUID instruction
  KVM: CPUID: Put maxphyaddr updating together with virtual address
    width checking
