virtio_pci: add check for common cfg size
Some buggy devices, the common cfg size may not match the features.
This patch checks the common cfg size for the
features(VIRTIO_F_NOTIF_CONFIG_DATA, VIRTIO_F_RING_RESET). When the
common cfg size does not match the corresponding feature, we fail the
probe and print error message.
