Check device having the feature of VIRTIO_CONSOLE_F_EMERG_WRITE before get config->emerg_wr. It is neccessary because sizeof(virtio_console_config) is 8 byte if VirtIOSerial doesn't have the feature of VIRTIO_CONSOLE_F_EMERG_WRITE(see virtio_serial_device_realize), read/write emerg_wr will lead to heap-over-flow.
