hv: vpci: sos could access low severity guest pci cfg space

Browse Source 
There're some cases the SOS (higher severity guest) needs to access the
post-launched VM (lower severity guest) PCI CFG space:
1. The SR-IOV PF needs to reset the VF
2. Some pass through device still need DM to handle some quirk.
In the case a device is assigned to a UOS and is not in a zombie state, the SOS
is able to access, if and only if the SOS has higher severity than the UOS.
