[PATCH vhost v1 1/2] virtio_pci: fix the common map size and add check for vq-reset

Now, the function vp_modern_map_capability() takes the size parameter, which corresponds to the size of virtio_pci_common_cfg. As a result, this indicates the size of memory area to map. However, if the _F_RING_RESET is negotiated, the extra items will be used. Therefore, we need to use the size o
