KVM: nVMX: Remove obsolete MSR bitmap refresh at nested transitions
Drop unnecessary MSR bitmap updates during nested transitions, as L1's APIC_BASE MSR is not modified by the standard VM-Enter/VM-Exit flows, and L2's MSR bitmap is managed separately. In the unlikely event that L1 is pathological and loads APIC_BASE via the VM-Exit load list, KVM will handle updating the bitmap in its normal WRMSR flows.
