virtio-input: free config list

Clear the list when finalizing. The list is created during realize with virtio_input_idstr_config() and later by further calls to virtio_input_init_config() and virtio_input_add_config(). This leak can be reproduced with device-introspect-test -p /x86_64/device/introspect/concrete. Signed-off-by: Marc-André Lureau <[email protected]> Reviewed-by: Gerd Hoffmann <[email protected]>
