hv: fix a bug about host/guest msr store/load

Browse Source 
Unify the handling of host/guest MSR area in VMCS. Remove the emum value
as the element index when there are a few of MSRs in host/guest area.
Because the index could be changed if one element not used. So, use a
variable to save the index which will be used.
