Rob Bradford a749063c8a vmm: Don't assume that resize_pipe is initialised
If the underlying kernel is old PTY resize is disabled and this is
represented by the use of None in the provided Option<File> type. In the
virtio-console PTY path don't blindly unwrap() the value that will be
preserved across a reboot.

Fixes: #3496
