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.
