HV: add uint32_t nr_bars to struct pci_vdev

Browse Source 
Use nr_bars instead of PCI_BAR_COUNT to check bar access offset.
As while normal pci device has max 6 bars, pci bridge only has 2 bars,
so for pci normal pci device, pci cfg offsets 0x10-0x24 are for bar access,
but for pci bridge, only 0x10-0x14 are for bar access (0x18-0x24 are
for other accesses).

Rename function:
 pci_bar_access --> is_bar_offset
