x86/KVM/VMX: Extend add_atomic_switch_msr() to allow VMENTER only MSRs

commit 989e3992d2eca32c3f1404f2bc91acda3aa122d8 upstream

The IA32_FLUSH_CMD MSR needs only to be written on VMENTER. Extend
add_atomic_switch_msr() with an entry_only parameter to allow storing the
MSR only in the guest (ENTRY) MSR array.
