hv: vpci: minor refine about MSI/MSI-X de-initialization

Browse Source 
About the MSI/MSI-X Capability, there're some fields of it would never been changed
once they had been initialized. So it's no need to reset them once the vdev instance
is still used. What need to reset are the fields which would been changed by guest
at runtime.
