Michael S. Tsirkin 7976a6d231 virtio-serial: fix virtio config size 
commit 9b70c1790a
    virtio-serial: switch to standard-headers

changes virtio_console_config size from 8 to 12 bytes:
it adds an optional 4 byte emerg_wr field.

As this crosses a power of two boundary, this changes the PCI BAR size,
which breaks migration compatibility with old qemu machine types.
It's probably a problem for other transports as well.

As a temporary fix, as we don't yet support this new field anyway,
simply make the config size smaller at init time.

Long terms we probably want something along the lines
of virtio_net_set_config_size.
