net: cdc-phonet: fix data-interface release on probe failure
[ Upstream commit c79a707072fe3fea0e3c92edee6ca85c1e53c29f ]
Set the disconnected flag before releasing the data interface in case
netdev registration fails to avoid having the disconnect callback try to
deregister the never registered netdev (and trigger a WARN_ON()).
Fixes: 87cf65601e17 ("USB host CDC Phonet network interface driver")
