Subject: [PATCH 0/2] KVM: nSVM: do not access MSR permission bitmap before KVM_RUN

Similar to what we need to do for VMX, the MSR permission bitmap
should not be accessed until the first KVM_RUN.  This is important
because the memory map might not be up-to-date at the time of
KVM_SET_NESTED_STATE.
