[PATCH v4 3/3] virtio_pci: drop callback sync on reset

[Michael S. Tsirkin]

The virtio core now synchronizes callbacks after reset,
so the PCI transports no longer need to do it themselves.

Notes (changelog):
    v3->v4:
        now includes modern transport (previously only legacy
        in patch 2, modern was in patch 3)
    
    v2->v3:
        split from v2 patch 2 - legacy part only
