When adding an MSR to the auto-load lists, update the MSR index in the list entry if and only if a new entry is being inserted, as 'i' can only be non-negative if vmx_find_loadstore_msr_slot() found an entry with the MSR's index. Unnecessarily setting the index is benign, but it makes it harder to see that updating the value is necessary even when an existing entry for the MSR was found. No functional change intended.
