[0/2] KVM: x86: Refactor MSR related helpers

Message

Refactor x86's MSR accessors to reduce the amount of boilerplate code
required to get/set an MSR, and consolidate the RDMSR/WRMSR emulation
for VMX and SVM since the code is functionally identical.

  KVM: x86: Add kvm_emulate_{rd,wr}msr() to consolidate VXM/SVM code
